Neanche Wallpaper Engine è al sicuro dalle campagne malware

18 June 2026 at 15:45

Di questi tempi non si può stare più tranquilli neanche a scaricare un semplice wallpaper: i ricercatori di Kaspersky hanno individuato una nuova campagna malware su Wallpaper Engine, l’app di sfondi avanzati molto popolare e apprezzata tra gli appassionati di videogiochi e personalizzazione estetica del proprio sistema, e uno dei principali fiori all’occhiello di Steam Workshop, la piattaforma di Valve dedicata alla condivisione di contenuti creati dalla community.

Wallpaper Engine è diversa dalle normali app di sfondi perché permette di impostare come wallpaper anche video, scene interattive, pagine Web e perfino dei veri e propri eseguibili. I cybercriminali sono stati inevitabilmente attratti da quest’ultima possibilità, includendo malware in pacchetti apparentemente innocui per Wallpaper Engine. Una volta installato lo sfondo, il codice dannoso può essere eseguito automaticamente in background senza destare sospetti, mentre l’applicazione “di facciata” continua a funzionare normalmente.

Le indagini dei ricercatori indicano che la campagna è in corso almeno da fine 2025. Sono stati individuati parecchi sfondi infetti con vari assortimenti di trojan per il furto di credenziali, backdoor, crypto miner e ransomware, alcuni dei quali avevano già accumulato decine di migliaia di download. Uno dei casi più pericolosi ha evidenziato che uno sfondo presentato come un semplice gioco installava in realtà una backdoor riconducibile alla famiglia DarkKomet. Il pacchetto installava anche una versione modificata di una libreria di sistema che serviva a individuare gli account Steam presenti sul computer e sottrarne le credenziali di accesso.

Google Chrome, aggiornamento di emergenza in distribuzione

18 June 2026 at 12:05

Nelle scorse ore Google ha rilasciato un aggiornamento di emergenza per Chrome che corregge ben 33 vulnerabilità, tra cui sette critiche, che potrebbero portare all’esecuzione di codice non autorizzato da remoto. Le nuove versioni del browser sono 149.0.7827.155 o 149.0.7827.156, e sono in distribuzione su Windows, macOS e Linux; per la maggior parte degli utenti si installeranno in automatico, come al solito, ma vista la gravità è consigliato accertarsene, usando il menu dei tre puntini in alto a destra e scegliendo Informazioni su Google Chrome.

La maggior parte delle falle critiche (sei su sette, addirittura) consistono in bug di gestione della memoria noti come “use-after-free”. Semplificando molto, un exploit potrebbe indurre il browser a usare aree di memoria che in teoria sarebbero già liberate, eseguendo codice non autorizzato che potrebbe causare danni in altre aree del sistema operativo. I bug sono stati rilevati in vari componenti fondamentali di Chrome, tra cui WebShare, WebView, Digital Credentials, Password Manager, File Input e Web Authentication. È particolarmente interessante osservare la tempestività con cui Google è intervenuta: tutti i bug sono stati riportati tra la fine di maggio e l’inizio di giugno - il più recente solo una settimana fa.

Google ha inoltre corretto svariati bug con un livello di gravità “solo” alto che coinvolgono WebRTC, il sistema dedicato alle comunicazioni audio e video in tempo reale, il framework delle estensioni e la piattaforma Chromoting dedicata all’accesso remoto. Tra i bug risolti figurano buffer overflow, letture fuori dai limiti di memoria, errori di validazione degli input e condizioni di race condition che potrebbero causare crash, perdite di dati sensibili o ulteriori compromissioni del sistema.

Windows 11 Insider Previews: What’s in the latest build?

15 June 2026 at 07:23

Windows 11 25H2 has been publicly released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out preview builds to members of its Windows Insider Program, allowing them to test out — and help shape — upcoming features.

Skip to the latest builds

Our story “How to preview and deploy Windows 10 and 11 updates” details how the Insider program has worked until now. However, Microsoft recently announced sweeping changes to the program that will include the ability to select which new features to test. As the first step, the company is introducing a new channel system and transitioning Insiders like so:

  • Beta Channel > Beta
  • Beta Channel (for devices on Windows 11 version 26H1) > Beta (26H1)
  • Dev Channel > Experimental
  • Canary Channel (28000 series) > Experimental (26H1)
  • Canary Channel (29500 series) > Experimental (Future Platforms)
  • Release Preview Channel > Release Preview 24H2/25H2
  • Release Preview Channel (for devices on Windows 11 version 26H1) > Release Preview (26H1)

This transition is happening over time, starting with the Dev Channel. See Microsoft’s blog post for more information about the transition.

Below you’ll find information about the Windows 11 preview builds that have been announced by Microsoft in the past six months. For each build, we’ve included the date of its release, which Insider channel it was released to, a summary of what’s in the build, and a link to Microsoft’s announcement about it.

Note: If you’re looking for information about updates being rolled out to all Windows 11 users, not preview builds for Windows Insiders, see “Windows 11: A guide to the updates.”

Here's some of their more interesting highlights for Clock, Media Player, Calculator, Voice Recorder, Photos, and Paint: The Photos app (version 2026.11060.2004.0): AI watermarking — "AI-generated or edited images can now carry a visible Copilot watermark. You choose Never, Always, or Ask Every Time in Settings, with a confirmation when saving. The watermarking is off by default in settings." Calculator (version 11.2605.9.0): More accurate square-root results. "Fixed rare cases where a calculation that should equal zero (like sqrt(2.25) — 1.5) returned a tiny leftover value instead...." Reliable launch after upgrading. "Fixed an issue where upgrading from much older versions could leave outdated settings that stopped the app from opening..." The Clock app (version 11.2605.9.0): "Timers keep counting after they hit zero — When a timer runs out, it now keeps counting up (for example, -00:27:31) so you can see how far past the time you've gone..." "Correct sun and moon icons during midnight sun — Fixed an icon that wrongly showed a moon during all-day daylight in polar regions... " "No more double announcements — Screen readers no longer read the timer value twice." Media Player (version 11.2605.14.0). "Playlists need a name — You can no longer accidentally save a playlist with a blank name."

Microsoft’s Patch Tuesday updates: Keeping up with the latest fixes

12 June 2026 at 16:56

Long before Taco Tuesday became part of the pop-culture vernacular, Tuesdays were synonymous with security — and for anyone in the tech world, they still are.  Patch Tuesday, as you most likely know, refers to the day each month when Microsoft releases security updates and patches for its software products — everything from Windows to Office to SQL Server, developer tools to browsers.

The practice, which happens on the second Tuesday of the month, was initiated to streamline the patch distribution process and make it easier for users and IT system administrators to manage updates.  Like tacos, Patch Tuesday is here to stay.

In a blog post celebrating the 20th anniversary of Patch Tuesday, the Microsoft Security Response Center wrote: “The concept of Patch Tuesday was conceived and implemented in 2003. Before this unified approach, our security updates were sporadic, posing significant challenges for IT professionals and organizations in deploying critical patches in a timely manner.”

Patch Tuesday will continue to be an “important part of our strategy to keep users secure,” Microsoft said, adding that it’s now an important part of the cybersecurity industry.  As a case in point, Adobe, among others, follows a similar patch cadence.

Patch Tuesday coverage has also long been a staple of Computerworld’s commitment to provide critical information to the IT industry. That’s why we’ve gathered together this collection of recent patches, a rolling list we’ll keep updated each month.

In case you missed a recent Patch Tuesday announcement, here are the latest six months of updates.

For June, Patch Tuesday means an IT scramble

Microsoft this month released 206 updates affecting Windows, Office, Exchange Server, and its developer tools — including three Windows vulnerabilities already publicly disclosed. That trio includes an elevation of privilege in the Collaborative Translation Framework (CVE-2026-45586), a denial of service in HTTP.sys (CVE-2026-49160), and a BitLocker security feature bypass (CVE-2026-50507). At the moment, none appear to be under active exploitation, but all three are rated “Exploitation More Likely.” 

Even without an exploited zero-day, the June 2026 Patch Tuesday release requires Patch Now recommendations for Windows, Office, and Exchange. The latter is back in the patch picture with a consolidated security update that Microsoft recommends installing “as soon as possible.”

More info is available here on Microsoft Security updates for June 2026.

For May, Patch Tuesday means 139 updates — but no zero-days

Microsoft this month released 139 updates affecting Windows, Office, .NET, and SQL Server (though there were no updates for Microsoft Exchange Server). Despite the absence of zero-days, the May Patch Tuesday update still requires Patch Now recommendations for Windows and Office. 

The combination of three unauthenticated network RCEs (Netlogon, DNS Client, and SSO Plugin for Jira and Confluence), four Word Preview Pane RCEs, the large TCP/IP vulnerability cluster, and the carry-over BitLocker recovery condition (still active on Windows 10 and Windows Server) warrants an accelerated deployment release schedule. 

More info is available here on Microsoft Security updates for May 2026.

Microsoft’s Patch Tuesday release for April is a whopper

Windows admins are going to be busy this month, dealing with the largest Patch Tuesday cycle in memory. The April release involves 165 updates and roughly 340 unique CVEs from Microsoft — including two zero-days, one of which is already being actively exploited in the wild. 

The Readiness team recommends “Patch Now” schedules for nearly every major product family: Windows, Office (with a zero-day), Microsoft Edge (Chromium), SQL Server, and Microsoft Developer Tools (.NET). April also brings Phase 2 of Microsoft’s Kerberos RC4 hardening with full enforcement set for July. There is a lot to cover, so here’s a useful infographic mapping the deployment risk for each platform.

More info is available here on Microsoft Security updates for April 2026.

For March, Patch Tuesday delivers fixes for 83 vulnerabilities

Microsoft’s March Patch Tuesday release addresses 83 vulnerabilities across Windows, Office, SQL Server, Azure, and .NET — with two publicly disclosed zero-days affecting SQL Server and .NET (though neither is being actively exploited in the wild.) Six additional vulnerabilities spanning the Windows Kernel, Graphics Component, SMB Server, Accessibility Infrastructure, and Winlogon are flagged as “Exploitation More Likely.”

The most significant change this month is the introduction of Common Log File System (CLFS) hardening with signature verification, which will affect how Windows handles log files across the operating system. More info on Microsoft Security updates for March 2026.

February’s Patch Tuesday release fixes 59 flaws, including 6 being exploited

The company’s Patch Tuesday release for February addresses 59 CVEs across the company’s product family — roughly half the volume of January’s 159 patches. Six vulnerabilities, affecting Windows Shell, MSHTML, Desktop Window Manager, Remote Desktop, Remote Access, and Microsoft Word, are already being actively exploited. (All five Critical-rated CVEs target Azureservices rather than Windows, however.) 

Both Windows and Office get a “Patch Now” recommendation, with CISA setting a March 3 enforcement deadline for all six exploited vulnerabilities. Two new enforcement timelines also take effect in April: Kerberos RC4 deprecation (CVE-2026-20833) and Windows Deployment Services hardening (CVE-2026-0386). More info on Microsoft Security updates for February 2026.

For January, Patch Tuesday starts off with a bang

The first Patch Tuesday release of 2026 addresses 112 CVEs across Microsoft’s product portfolio, including eight rated critical and three zero-day vulnerabilities. One zero-day (CVE-2026-20805), an information disclosure flaw in the Desktop Window Manager, is already under active exploitation, prompting CISA to add it to the Known Exploited Vulnerabilities catalog with a remediation deadline of Feb. 3, 2026. (Note: 95 of the vulnerabilities affect Windows.) More info on Microsoft Security updates for January 2026.

For June, Patch Tuesday means an IT scramble

12 June 2026 at 16:52

Microsoft this week released 206 updates affecting Windows, Office, Exchange Server, and its developer tools —  including three Windows vulnerabilities already publicly disclosed. That trio includes an elevation of privilege in the Collaborative Translation Framework (CVE-2026-45586), a denial of service in HTTP.sys (CVE-2026-49160), and a BitLocker security feature bypass (CVE-2026-50507). At the moment, none appear to be under active exploitation, but all three are rated “Exploitation More Likely.” 

Even without an exploited zero-day, the June 2026 Patch Tuesday release requires Patch Now recommendations for Windows, Office, and Exchange. The latter is back in the patch picture with a consolidated security update that Microsoft recommends installing “as soon as possible.” 

The Readiness team suggests testing start with domain controllers, Hyper-V hosts, anything self-hosting on HTTP.sys, and Outlook-heavy desktops —  in that order. To help navigate these changes, here’s a useful infographic detailing the risks of deploying the updates to each platform.

(More information about recent Patch Tuesday releases is available here.)

Known issues

This June release note from Microsoft flags known issues with three updates:

  • KB5094128 — BitLocker recovery prompt on first restart (Windows Server 2022). The PCR7 condition we have tracked since April is still live on the platforms that did not receive May’s Boot Manager servicing fix. Devices with BitLocker enabled on the OS drive, the Group Policy “Configure TPM platform validation profile for native UEFI firmware configurations” set with PCR7 included, and System Information reporting Secure Boot State PCR7 Binding as “Not Possible” may prompt for the recovery key on the first restart after installing this update.
  • KB5094127 — Windows 10 21H2/22H2. The release note carries a known-issue flag, too, with Windows 10 in the same boat as Server 2022: it has not received the Boot Manager servicing improvement that closed the BitLocker/PCR7 recovery condition on Windows 11. So, that same Group Policy configuration remains the trigger to check before deployment.
  • KB5094125/KB5094128 — WSUS synchronization error details suppressed (Windows Server 2025 and 2022). WSUS no longer displays synchronization error details in its reporting. This is deliberate: the functionality was “temporarily removed to address the Remote Code Execution Vulnerability, CVE-2025-59287.” Microsoft offered no workaround.

One continuing advisory from May remains in effect: Windows Update can still replace manually installed graphics drivers with older OEM versions from the Windows Update catalogue.

Major revisions and mitigations

Unlike last month, this patch cycle delivered two genuine revisions and a cluster of out-of-band fixes that require action:

  • Microsoft Teams Spoofing (CVE-2026-32185) — revised to version 3.0 on May 21. Microsoft announced the availability of the security update for Teams for Android; customers running affected versions should install it. If your mobile fleet runs Android, this is the action item.
  • Microsoft Defender out-of-band cluster (May 19–21) — a Critical remote code execution flaw (CVE-2026-45584), plus an elevation of privilege (CVE-2026-41091) and a denial of service (CVE-2026-45498).
  • SharePoint RCE (CVE-2026-45659) — a separate out-of-band fix also posted on May 21. SharePoint admins had three distinct security notices in a fortnight. The recommendation: deploy these clustered but separate patches as a single unit.

Interestingly, there were two omissions from last month’s list:

  • SharePoint Server RCE (CVE-2026-47294) — published May 29 with the note that it “was addressed by updates that were released in May 2026, but the CVE was inadvertently omitted from the May 2026 Security Updates.”
  • Windows DWM Core Library Information Disclosure (CVE-2026-48566) — also fixed in May, also left off the May list.

That makes two months running: the Patch Tuesday list is never final. The June release itself also carried a substantive revision:

  • Remote Desktop cluster re-issued for Windows 11 26H1 — five RDP/RDS CVEs from 2024–2025, including two Critical RCEs (CVE-2024-49123, CVE-2024-49132) and the RDP Server RCE (CVE-2024-43582). If you are running 26H1, the June cumulative closes these older CVEs.

Windows lifecycle and enforcement updates

Given the month SharePoint just had, SharePoint 2016/2019 require some of the cycle’s most active patching on a platform with one update left. If migration is not already in progress, July’s final update is the deadline. Here are the other key dates:

  • The 2011 KEK CA expires on June 24, and the UEFI CA for third-party boot loaders follows three days later, with the Windows Production PCA for the boot manager coming up October. 19. Devices that have not taken the Windows UEFI CA 2023 key updates under CVE-2023-24932 lose the ability to receive updated boot components once the certificates lapse. This is a big deal.
  • With just one Patch Tuesday to go, SharePoint Server 2016 and 2019, Project Server 2016 and 2019, SQL Server 2016, and SQL Server 2014 ESU Year 2 all reach end of support on July 14. (InfoPath 2013, SharePoint Designer 2013, and Visual Studio 2022 17.12 LTSC go with them.)
  • Kerberos RC4 hardening (CVE-2026-20833) moves from default-hardening to its enforcement phase next month. Accounts still depending on RC4 service tickets have weeks, not months.
  • The graphics-driver targeting change (four-part to two-part Hardware IDs) pilots to September 2026, with broader enforcement planned for Q4 2026 to Q1 2027; until then, Windows Update can still downgrade manually installed display drivers.

This month’s release is a security-only release with a clear feature focus: the Remote Desktop client. The Remote Desktop ActiveX control (mstscax.dll) is the most patched component this cycle with five separate updates (see below). 

The secondary theme is Windows authentication, with three updates to the NTLM security package. Every Windows binary this month reports no functional changes, so the work is pure regression validation. Lower-risk patches reach DHCP, telephony, Hyper-V, UDF and Projected File System storage, and the graphics stack.

Remote Desktop client

The Remote Desktop client (mstscax.dll) draws a high-risk flag that lands specifically on printer redirection — the path that maps a client’s local printers into a remote session. A regression here typically shows as missing redirected printers, failed print jobs, or a hang on connect or reconnect. The wider Remote Desktop stack is also updated, including RemoteApp and clipboard redirection (rdpclip.exe, RdpCoreTS.dll) and Remote Desktop Licensing (lserver.dll). So, be sure to validate connection, session, and licensing together.

A passing run is a remote session that connects, redirects printers, prints, and survives a reconnect with no crashes or missing devices.

  • Connect with Remote Desktop Connection (mstsc.exe) to a test host, enable printer redirection in Local Resources, and confirm redirected printers appear in the session.
  • Print a test page from an app in the session to a redirected printer; repeat with two or more client printers installed.
  • Disconnect and reconnect the session, then confirm the redirected printers are still present and usable.
  • Repeat the printer test in both a full desktop session and a RemoteApp session.
  • Exercise general remote access: connect through a Remote Desktop Gateway, use VMConnect to reach a VM, and verify clipboard and device redirection.
  • On a Remote Desktop Licensing server, confirm clients connect with licensing enabled, across Per User and Per Device modes.

Windows authentication (NTLM)

Three updates touch the NTLM security support provider (msv1\_0.dll), the module behind network authentication when Kerberos is not used. Authentication changes are regression-sensitive: the failure modes are logon failures, broken file-share or RDP access, and application sign-in problems. Validate across domain-joined and workgroup machines.

  • Sign in to domain-joined and standalone machines with domain, local, and cached credentials after a reboot.
  • Access SMB file shares by host name and IP, including paths that fall back to NTLM, and confirm authenticated reads and writes.
  • Authenticate to a Remote Desktop host and to line-of-business applications that rely on integrated Windows authentication.
  • Watch the Security event log for new logon-failure or audit anomalies during the test window.

Other Windows components

The remaining updates carry no functional changes, so cover them with routine regression by area.

  • Networking: exercise DHCP lease, renewal, and release on IPv4 and IPv6 (dhcpcore), sustained socket traffic over the WinSock driver (afd.sys, two updates), HTTP.sys request handling under IIS, and TAPI telephony integrations (tapisrv.dll).
  • Virtualization: boot Generation 1 and Generation 2 VMs, including nested virtualization, to cover the Hyper-V hypervisor (hvix64/hvax64), and connect a VM through an external virtual switch (toggling NIC RSS) to cover vmswitch.sys.
  • Storage and filesystems: read and write UDF-formatted media (udfs.sys), exercise the Projected File System minifilter (prjflt.sys), and validate cloud files hydration and Work Folders sync (cldflt.sys, workfolders.exe), including a ReFS volume with BitLocker enabled.
  • Graphics and shell: run GPU-accelerated and 2D rendering workloads to cover Direct2D (d2d1.dll), GDI+ (gdiplus.dll), the Desktop Window Manager (dwmcore.dll), the Windows Imaging Component (windowscodecs.dll), and UI Automation (UiaManager.dll); watch for artifacts and accessibility regressions.
  • Notifications and input: open apps that raise toast and push notifications (wpnapps.dll, wpncore.dll) and verify Text Services Framework input across keyboard layouts and IMEs (msctf.dll).

Microsoft Office & SharePoint

June’s Office updates are MSI editions only: Excel 2016 (KB5002877), Word 2016 (KB5002879), Office 2016 shared components (KB5002878, KB5002852, and the rich-edit control KB5002578), and Office Online Server 2019 (KB5002875). The shared Office 2016 component updates also apply to the SharePoint Server 2016, 2019, and Subscription Edition baselines. No Critical non-security client release ships this cycle, and Click-to-Run estates are unaffected.

  • Open complex Excel workbooks with formulas, macros, and external data connections; save and reopen to verify integrity.
  • Edit Word documents with embedded objects, tracked changes, and rich formatting that exercises the rich-edit control.
  • On the SharePoint Server baselines (2016, 2019, Subscription Edition) and Office Online Server, validate document library operations, co-authoring, and browser-based viewing and editing.
  • Confirm that Office add-ins and line-of-business integrations continue to operate.

Developer tools and databases

June’s fixes update the .NET SDK across the 8.0, 9.0, and 10.0 servicing lines (8.0.422, 9.0.315, 10.0.301), and ships SQL Server GDR security updates spanning SQL Server 2016 SP3 through SQL Server 2025, in both RTM+GDR and cumulative-update+GDR branches.

  • After installing the .NET SDK update, build and run representative applications and confirm existing projects compile and execute normally.
  • For SQL Server, install the GDR update onto the matching baseline or cumulative-update branch, then restart the service and run standard transactions.
  • Verify a backup and restore, confirm Always On availability groups stay healthy, and test patch install and removal on each servicing branch.

The Readiness team suggests that this month’s testing lead with Remote Desktop. The client is both the most-patched component and the sole High Risk item, so give it a focused regression pass centered on printer redirection, then broaden to general connectivity, RemoteApp, clipboard and device redirection, gateway access, and licensing. 

The NTLM authentication updates are the second priority: validate domain and standalone logon, file-share access, and application sign-in. Everything else is a no-functional-change security update, so cover networking, Hyper-V, storage, and graphics with routine regression. Office is MSI-only, with Click-to-Run untouched, and the .NET and SQL Server updates round out the developer and database estate.

Each month, we break down the update cycle into product families (as defined by Microsoft) with the following basic groupings:

Browsers

Microsoft Edge released the stable version (149.0.4022.52) on June 4, per the Edge security release notes. Nothing ships for Internet Explorer, which remains retired. This cycle is unusually lopsided: just one Edge-engineered CVE against a very large Chromium upstream flow:

  • CVE-2026-47644 — Copilot Chat (Microsoft Edge) — Information disclosure (CVSS 6.5, rated critical). For the second month running, Copilot Chat in Edge supplies the headline browser issue (May’s was CVE-2026-33111); Microsoft addresses the Copilot service component, with the browser update completing the fix.
  • Chromium upstream — 407 CVEs relayed through MSRC this cycle, spanning the weekly Chrome release cadence since the May report: use-after-free, out-of-bounds read/write, type confusion, and policy bypass across V8, Blink, PDFium, WebRTC, ANGLE, and DevTools. The same fixes ship in the Chrome Stable channel; see the Chrome release blog for the upstream notes.

The Chromium volume looks alarming but is routine plumbing —  it flows to Edge through its own auto-update channel. Add these updates to your standard release schedule for Edge-managed environments.

Windows

Microsoft addressed 119 vulnerabilities in Windows this month, 22 rated critical and 97, important —  nearly double May’s count. Elevation of privilege again dominates by volume (49 entries), followed by remote code execution (28), information disclosure (16), security feature bypass (15), denial of service (6), and a handful of spoofing and tampering entries. All three of June’s publicly disclosed zero-days land here:

  • CVE-2026-45586 — Collaborative Translation Framework (CTFMON) — Elevation of privilege (CVSS 7.8, publicly disclosed).
  • CVE-2026-49160 — HTTP.sys — Denial of service (CVSS 7.5, publicly disclosed).
  • CVE-2026-50507 — BitLocker — Security feature bypass (CVSS 6.8, publicly disclosed) —  BitLocker’s third entry this month, keeping it on the radar alongside the PCR7 known issue.

At the feature level, the critical risks are concentrated in nine areas:

  • Remote Desktop Client — the largest single cluster: 11 CVEs, 7 rated critical, led by CVE-2026-47289 and CVE-2026-42985 (both CVSS 8.8, the latter “Exploitation More Likely”).
  • Windows Kernel — CVE-2026-45657, remote code execution at CVSS 9.8, the joint-highest Windows score this cycle.
  • HTTP.sys — CVE-2026-47291, unauthenticated remote code execution (CVSS 9.8, “Exploitation More Likely”) in the kernel-mode web server underpinning IIS, WinRM, and anything self-hosting on http.sys — paired with the disclosed DoS above.
  • DHCP Client — CVE-2026-44815, remote code execution at CVSS 9.8.
  • Active Directory Domain Services — CVE-2026-45648, remote code execution (CVSS 8.8) on the directory itself, with the Kerberos KDC adding a separate critical RCE (CVE-2026-47288).
  • Hyper-V — three critical RCEs (CVE-2026-45607, CVE-2026-45641, CVE-2026-47652, up to CVSS 8.4) — guest-to-host risk on virtualization hosts.
  • Windows Graphics Component — two critical RCEs (CVE-2026-44803, CVE-2026-44812, CVSS 7.8), both “Exploitation More Likely” vulnerabilities reachable through Office rendering paths.
  • Windows Deployment Services — CVE-2026-42987, remote code execution (CVSS 8.1).
  • Cryptographic Services and Device Health Attestation — critical elevation-of-privilege entries (CVE-2026-44810, CVSS 8.4; CVE-2026-33828, CVSS 7.8) in trust-anchor components.

Given the publicly disclosed vulnerabilities this month, add this Windows update to your Patch Now schedule.

Office

Microsoft released 53 Office CVEs this month — 10 critical, 43 important. Remote code execution again leads (24 entries), but the surprise is spoofing at 20 entries, almost all of it SharePoint. (SharePoint Server appears in 30 of the 53 CVEs this cycle.) The rest split across information disclosure (6), elevation of privilege (2), and a security feature bypass.

Add these Office updates to your Patch Now deployment, prioritizing Outlook-heavy desktops and SharePoint farms.

Microsoft Exchange and SQL Server

The pattern inverts from May: SQL Server receives nothing (no patches at all), while Exchange Server — absent in May — returns with a consolidated security update carrying seven CVEs for on-premises builds (Exchange Server 2016 CU23 and Exchange Server 2019), plus one cloud-side critical:

  • CVE-2026-45504 — Exchange Server — Elevation of privilege (CVSS 8.8). The headline on-premises entry.
  • CVE-2026-45503 and CVE-2026-47631 — Exchange Server — Information disclosure and spoofing, each CVSS 8.1.
  • CVE-2026-45583 — Exchange Server — Remote code execution (CVSS 7.5), with three further spoofing/information-disclosure entries (CVE-2026-45500, CVE-2026-45501, CVE-2026-45502) rounding out the set.
  • CVE-2026-48579 — Exchange Online — Information disclosure (CVSS 9.1, rated critical) —  addressed service-side, no customer action.

Microsoft also revised the May Exchange spoofing entry (CVE-2026-42897) to point at this same June security update, with the recommendation to install “as soon as possible.” Add the June Exchange SU to your Patch Now schedule.

Developer tools

Microsoft released 10 CVEs across its developer tooling this month, all rated important —  though the top score outranks most of this cycle’s criticals, and the concentration in Visual Studio Code (seven of 10 entries) continues last month’s pattern:

  • Visual Studio Code — seven entries led by CVE-2026-47281, an elevation of privilege at CVSS 9.6 —  the highest developer-tools score in months. Behind it: CVE-2026-45482, a security feature bypass in the GitHub Copilot Chat extension (CVSS 8.4); CVE-2026-47292, remote code execution in the MSSQL extension (CVSS 7.8); a second elevation of privilege (CVE-2026-40376, CVSS 7.5); and security-feature-bypass, tampering, and information-disclosure entries (CVE-2026-48569, CVE-2026-47287, CVE-2026-47284).
  • Microsoft .NET on Windows has three entries: CVE-2026-45490, a .NET SDK elevation of privilege (CVSS 7.8) across .NET 8.0, 9.0, and 10.0; CVE-2026-45591, an ASP.NET Core denial of service (CVSS 7.5); and CVE-2026-45491, a .NET tampering issue (CVSS 6.2).

Add these Microsoft updates to your standard developer update release plan.

Adobe (and third-party updates)

Adobe released APSB26-63 for Acrobat and Reader this cycle, fixing critical code-execution flaws; Adobe reports no exploitation in the wild. Add it to your standard third-party schedule. This is a big (fat) Windows update this month (and yes, I think that AI has something to do with the number of these patches). 

Good luck with your deployments.

Windows 11: A guide to the updates

9 June 2026 at 15:50

A Windows launch isn’t the end a process — it’s really just the beginning. Microsoft continually works on improving Windows 11 by fixing bugs, releasing security patches, and occasionally adding new features.

In this story we summarize what you need to know about each update released to the public for the most recent mainstream version of Windows 11 — currently version 25H2 — over the past year. (We also cover updates for Windows 11 26H1, a targeted release of Windows for devices with specific chips.) For each build, we’ve included the date of its release and a link to Microsoft’s announcement about it. The most recent updates appear first.

The easiest way to install updates is via Windows Update. Not sure how? See “How to handle Windows 10 and 11 updates” for full instructions. Note that Windows 11 version 25H2 is being released as a phased rollout and may not be available to you in Windows Update yet.

If you’re still using Windows 10, see “Windows 10: A guide to the updates.” And if you’re looking for information about Insider Program previews for upcoming feature releases of Windows 11, see “Windows 11 Insider Previews: What’s in the latest build?”

Updates for Windows 11 24H2, 25H2, and 26H1

Windows 11 KB5094126 (OS Builds 26200.8655 and 26100.8655)

Release date: June 9, 2026

In this build, for devices running Windows 24H2 and 25H2, Windows quality updates now include additional high-confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.

(For more about Secure Boot certificate upgrades, see the Computerworld story “FAQ: What you need to know about expiring Windows Secure Boot certificates.”)

The build also fixes one bug that could have resulted in Stop errors HYPERVISOR_ERROR (0x20001) and KMODE_EXCEPTION_NOT_HANDLED (0x1E) after installing KB5089573 on some devices during system restarts, virtual machine operations, or while running some gaming applications.

The build has one known issue, in which devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key.

It also has a wide variety of security updates. For details, see Microsoft’s Security Update Guide and June 2026 Security Updates.

What IT needs to know: Because this is a security update, it should be applied relatively soon. Over the next few weeks, check for reports about problematic issues, and if all seems well, apply the update.

(Get more info about KB5094126.)

Windows 11 26H1 KB5095051 (OS Build 28000.2269)

Release date: June 9, 2026

This update, for devices on Windows 11 version 26H1, improves the reliability of BitLocker Drive Encryption testing by ensuring that all required files are available for the USB BIOS logo test.

It also has a wide variety of security updates. For details, see June 2026 Security Updates.

What IT needs to know: Because this is a security update, it should be applied relatively soon. Over the next few weeks, check for reports about problematic issues, and if all seems well, apply the update.

(Get more info about KB5095051.)

KB5089573 (OS Builds 26200.8524 and 26100.8524) Preview

Release date: May 26, 2026

With this update, Windows quality updates include additional high-confidence device targeting data, making more devices eligible to receive new Secure Boot certificates. The old certificates expire at the end of June: see Computerworld’s FAQ for details. The build also adds Group Policy and MDM settings that IT admins can enable to limit the Secure Boot service data sent to Microsoft. (See Microsoft documentation.)

This update also includes a wide variety of new features being rolled out gradually, including Shared Audio, which enables two Bluetooth audio devices to connect to a single Windows 11 PC at the same time; Multi-App Camera, which allows multiple applications to access the camera stream simultaneously; improved visibility into NPU usage in Task Manager; and several performance and behavior improvements for Windows Hello.

There is one known issue in the update, in which after you install update KB5089549, some devices might fail to complete installation with error code 0x800f0922. This issue occurs on devices that have limited free space on the EFI System Partition (ESP), especially if it has 10MB or less available.

Windows 11 25H2

At the end of September, Microsoft upgraded Windows 11 from version 24H2 to 25H2, in a slow rollout that could take months to complete. Typically in the past, Microsoft would introduce new features in a once-a-year update like this. That’s not the case with 25H2, though.

Microsoft has been introducing new features in smaller updates all year round, so 25H2 doesn’t include any major new features. Rather, it includes all the new features that have accumulated in all those smaller updates.

As the company explains, “While this update doesn’t introduce major new features, it activates enhancements that have been gradually rolled out over the past year ensuring your device is up to date with the latest refinements.”

Here are some of the most important features in 25H2 that have been introduced for end users and IT pros since 24H2 was released last fall:

New features for users:

  • File Explorer has several useful new features, notably AI actions, which can edit images or summarize documents. AI options such as Blur background, Erase objects, and Remove background are all now displayed in the context menu.
  • Task Manager gets a number of minor tweaks, including performance improvements when changing the sort order of processes.
  • You can now display the apps that have recently used on-device generative AI models provided by Windows. You can also choose which apps are permitted to use the generative AI technologies. To do that and more, go to Settings > Privacy & security > Text and Image Generation.

New features for IT:

  • IT admins can use policy-based tools to easily remove preinstalled Microsoft Store apps from Enterprise and Education editions of Windows 11, version 25H2 and later. This can streamline device provisioning and prevent removed apps such as Microsoft Clipchamp, Media Player, and Microsoft Teams from being reinstalled. For more information, see Policy-based removal of preinstalled Microsoft Store apps and RemoveDefaultMicrosoftStorePackages in the ApplicationManagement Policy CSP.
  • Enterprise access points now support Wi-Fi 7, which enables increased speeds, greater throughput, improved reliability, and enhanced security. For details, see https://aka.ms/WiFi7forEnterprise.
  • Windows Backup for Organizations is now generally available.
  • A new feature called Quick Machine Recovery can recover Windows devices when they encounter critical errors that prevent them from booting. Quick machine recovery searches for remediations in the cloud and recovers from widespread boot failures, reducing the burden on IT admins on cases when multiple devices are affected. For more information, see Computerworld’s Quick Machine Recovery explainer.

Windows 10: A guide to the updates

9 June 2026 at 15:40

Windows 10 has reached the end of mainstream support, which means most users will no longer receive new features, bug fixes, or security updates. Microsoft encourages businesses and individuals to upgrade to Windows 11.

Another option is to purchase extended security updates for Windows 10. Those enrolled in the Windows 10 Extended Security Updates (ESU) program will receive monthly security updates, but no new feature releases.

In this story we summarize what you need to know about each update released for the most recent versions of Windows 10 — versions 22H2 and 21H2. (Microsoft releases updates for those two versions together.) For each build, we’ve included the date of its initial release and a link to Microsoft’s announcement about it. The most recent updates appear first.

For details about how to install and manage Windows updates, see “How to handle Windows 10 and 11 updates.”

Updates to Windows 10 versions 21H2 and 22H2

As of November 2025, only computers enrolled in the Windows 10 ESU program (or those with a Windows 10 Enterprise LTSC 2021 or 2024 license) will receive Windows 10 updates.

Windows 10 November 2021 Update (version 21H2)

Release date: November 16, 2021

Version 21H2, called the Windows 10 November 2021 Update, is the second feature update to Windows 10 released in 2021. Here’s a quick summary of what’s new:

  • Wi-Fi security has been enhanced with WPA3 H2E standards support.
  • GPU compute support has been added in the Windows Subsystem for Linux (WSL) and Azure IoT Edge for Linux on Windows (EFLOW) deployments for machine learning and other compute-intensive workflows.

There are also a number of features designed for IT and business:

  • Windows Hello for Business has a new deployment method called cloud trust that simplifies passwordless deployments.
  • For increased security, there have been changes to the Universal Windows Platform (UWP) VPN APIs, which includes the ability to implement common web-based authentication schemes and to reuse existing protocols.
  • Apps can now be provisioned from Azure Virtual Desktop. This allows those apps to run just like local apps, including the ability to copy and paste between remote and local apps.
  • The release closes the gap between Group Policy and mobile device management (MDM) settings. The device configuration settings catalog has been updated to list more than 1,400 settings previously not available for configuration via MDM. The new MDM policies include administrative template (ADMX) policies, such as App Compat, Event Forwarding, Servicing, and Task Scheduler.
  • An upgrade to Windows 10 Enterprise includes Universal Print, which now supports print jobs of up to 1GB or a series of print jobs from an individual user that add up to 1GB within any 15-minute period.
  • Universal Print integrates with OneDrive for web and Excel for web. This allows users of any browser or device connected to the internet to print documents hosted in OneDrive for web to a printer in their organization without installing printer drivers on their devices.

Microsoft has also announced that starting with this release, Windows 10 will get feature updates only once a year.

Windows 10 May 2021 Update (version 21H1)

Release date: May 18, 2021

Version 21H1, called the Windows 10 May 2021 Update, is the most recent update to Windows 10. This is a relatively minor update, but it does have a few new features.

Here’s a quick summary of what’s new in 21H1:

  • Windows Hello multicamera support: If you have an external Windows Hello camera for your PC, you can set the external camera as your default camera. (Windows Hello is used for signing into PCs.) Why should this change matter to you? If you have an external camera, you probably bought it because it’s superior to the built-in, internal one on your computer. So with this change, you’ll be able to use the more accurate camera for logging into your PC.
  • Improved Windows Defender Application Guard performance: Windows Defender Application Guard lets administrators configure applications to run in an isolated, virtualized container for improved security. With this change, documents will open more quickly. It can currently take up to a minute to open an Office document in it.
  • Better Windows Management Instrumentation (WMI) Group Policy Service support: Microsoft has made it easier for administrators to change settings to support remote work.

Windows 10 October 2020 Update (version 20H2)

Release date: October 20, 2020

Version 20H2, called the Windows 10 October 2020 Update, is the most recent update to Windows 10. This is a relatively minor update but does have a few new features.

Here’s a quick summary of what’s new in 20H2:

  • The new Chromium-based version of the Microsoft Edge browser is now built directly into Windows 10.
  • The System page of Control Panel has been removed. Those settings have been moved to the Settings app.
  • The Start menu’s tiled background will match your choice of Windows themes. So the tiled background will be light if you’re using the Windows 10 light theme and dark if you’re using the Windows 10 dark theme.
  • When you use Alt-Tab, Edge will now display each tab in your browser in a different Alt-Tab window. Previously, when you used Alt-Tab, Edge would get only a single window. You can change this new behavior by going to Settings > System > Multitasking.
  • When you pin a site to the taskbar in Edge, you can click or mouse over its icon to see all your browser tabs that are open for that website.
  • When you detach a keyboard on a 2-in-1 device, the device will automatically switch to the tablet-based interface. Previously, you were asked whether you wanted to switch. You can change that setting by going to Settings > System > Tablet.
  • The Your Phone app gets a variety of new features for some Samsung devices. When using one of the devices, you can interact with the Android apps on your phone from the Your Phone app on Windows 10.

What IT needs to know: Windows 10 version 20H2 also has a variety of small changes of note for sysadmins and those in IT.

  • IT professionals who administer multiple mobile devices get a new Modern Device Management (MDM) “Local Users and Groups” settings policy that mirrors options available for devices that are managed through Group Policy.
  • Windows Autopilot, used to set up and configure devices in enterprises, has gained a variety of small enhancement, including better deployment of HoloLens devices, the addition of co-management policies, enhancements to Autopilot deployment reporting, and the ability to reuse Configuration Manager task sequences to configure devices.
  • Microsoft Defender Application Guard now supports Office. This allows untrusted Office documents from outside an enterprise to launch in an isolated container to stop potentially malicious content from compromising computers or exploiting personal information found on them.
  • Latest Cumulative Updates (LCUs) and Servicing Stack Updates (SSUs) have been combined into a single cumulative monthly update, available via Microsoft Catalog or Windows Server Update Services.
  • Biometric sign-on has been made more secure. Windows Hello now has support for virtualization-based security for certain fingerprint and face sensors, which protects, isolates, and secures a user’s biometric authentication data.

Windows 10 May 2020 Update (version 2004)

Release date: May 27, 2020

Version 2004, called the Windows 10 May 2020 Update, is the most recent update to Windows 10. This is a relatively minor update but does have a variety of new features for both users and system administrators. For more details, see: “Review: Windows 10 May 2020 Update delivers little tweaks that add up to… well, not a lot.”

Here’s a quick summary of what’s new in 2004:

  • Cortana now runs as a standalone app in a resizable window. It also loses a variety of capabilities, such as playing music, controlling home devices, and working on the lock screen.
  • Task Manager now displays new information, including the temperature of your GPU and your disk type.
  • Settings gets many small tweaks, including adding a header with account information, and a redone network status page that combines information that used to be found on multiple pages, such as your IP address, current connection properties and data usage.
  • The Windows Subsystem for Linux (WSL) gets more features. It now uses a real Linux kernel, and is faster than previously.
  • IT can now take advantage of Windows Hello biometrics logins rather than passwords, by setting that up as the default on enterprise devices.
  • Installing and setting up Windows for others has been made easier thanks to new controls added to Dynamic Update, which can lead to less downtime during installation for users.
  • A variety of new commands have been given to PowerShell for Delivery Optimization, a Windows networking service that reduces bandwidth consumption by sharing the work of downloading update and upgrade packages among multiple devices in business deployments.
  • The security of the Chromium version of Edge has been improved, thanks to porting Application Guard to it.

Windows 10 November 2019 Update (version 1909)

Release date: Nov. 12, 2019

Version 1909, called the Windows 10 November 2019 Update, is the most recent update to Windows 10. There are very few new features in this update, making it more like a service pack of old than a feature update. At this point it’s not clear whether in the future there will be one full-featured update and one service-pack-like update per year or whether Microsoft will go back to its two-feature-updates-a-year schedule. For more details, see “What we know so far about the unusual Windows 10 1909” and “5 unanswered questions about Windows 10 1909.”

Here’s a quick summary of what’s new for users in 1909.

  • It lets you create calendar events straight from the taskbar. To do it, click the time on the taskbar and you’ll open the Calendar view. Now click a date and time, then type the event’s name into the text box. You’ll also be able to choose the date, time and location.
  • When you type a search into the search box, it will now search through files in your OneDrive account as well as on your PC. Also, as you type, a drop-down menu with suggested files appears. Click a file to open it.
  • Voice assistants in addition to Cortana, including Amazon’s Alexa, will be able to run on Windows 10’s lock screen.
  • Under-the-hood improvements should speed up the performance of some PCs, as well as increase the battery life in some laptops.
  • The Start Menu has gotten minor tweaks. When you hover over items in the navigation pane on the left side of the menu, the items clearly show what you’re about to click.

What IT needs to know: The following features in 1909 are of note for IT staff.

  • Windows containers no longer need to have their host and container versions match. That requirement restricted Windows from supporting mixed-version container pod scenarios. Previously, containers from older versions of Windows 10 couldn’t be run on newer versions of Windows 10. In this update, it’s possible, so that a container made using 1903, for example, can be run on 1909.
  • Windows Defender Credential Guard, which protects enterprise users’ logins and credentials against theft, is now available for ARM64 devices. Some Windows 10 convertible PCs use ARM64.
  • Enterprises can now use Microsoft’s Intune enterprise mobility management (EMM) service to allow devices running Windows 10 in S mode to install and run Win32 (desktop) apps. Before this, S Mode only allowed devices to run apps from the Microsoft Store. Microsoft Store apps don’t run on the desktop.
  • The security of BitLocker encryption has been improved. Whenever BitLocker is used to encrypt a device, a recovery key is created, but before this security improvement, it was possible for an unauthorized user to get access to the recovery key and decrypt the device. Now, PCs have additional security if a key is exposed. Here’s how Microsoft explains the change: “Key-rolling or Key-rotation feature enables secure rolling of Recovery passwords on MDM managed AAD devices upon on demand request from Microsoft Intune/MDM tools or upon every time recovery password is used to unlock the BitLocker protected drive.”

There are two known issues in this update: one in which some users cannot set Win32 program defaults for certain app and file type combinations using the Open with… command or Settings > Apps > Default apps, and another in which Microsoft Notepad and other Win32 programs cannot be set as default applications.

Windows 10 October 2018 Update (version 1809)

Release date: October 2, 2018; paused October 5; re-released November 13, 2018

Version 1809, called the Windows 10 October 2018 Update, is the feature update that preceded the May 2019 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

  • A new, powered-up Windows Clipboard can hold multiple clips, store clips permanently, let you preview clips and choose which one you’d like to paste into a document, and share clips across Windows 10 devices.
  • A new screenshot and annotation tool called Snip & Sketch lets you capture and annotate the entire screen, a rectangular portion of the screen or a freehand-drawn portion of it. After you take a screen capture, you can annotate it and then save it to a file, copy it to the Clipboard, open it in another program or share it via email, social media and other methods.
  • Storage Sense, which helps save storage space, now works with OneDrive Files On-Demand to clean out files you’ve downloaded from OneDrive cloud storage to your PC but that you don’t use any longer. You can choose how long you would like the cloud files to stay on your PC unused before you want them deleted, from never to 60 days.
  • The Microsoft Edge browser lets you set autoplay permissions for sound and video on websites on a site-by-site basis. It also lets you look up word definitions in its built-in eReader for books and PDFs, and mark up PDFs and books using a highlighter and by adding notes.
  • The new Your Phone app links Windows 10 devices to iOS and Android phones. It allows you to start web browsing on an iOS or Android device and then continue where you left off on your PC. It also lets you view photos on your Android phone from your Windows 10 PC.
  • Search Previews have been powered up slightly. You no longer need to click to display the preview panel; it opens automatically. It also now shows files found on your PC.
  • Smaller changes include a new dark theme for File Explorer; the addition of the SwiftKey swipe keyboard, which lets you enter text by swiping a finger across an onscreen keyboard; updates that are less intrusive; and faster sign-ins on shared PCs.

What IT needs to know: There are few significant changes that affect IT in the Windows 10 October 2018 Update, other than New Microsoft Edge Group Policies that let admins enable and disable full-screen mode, printing, the favorites bar, and browser history saves. IT can also allow or ban Edge extensions (not that there are many available) and configure the Home button and new tab page and startup options.

Windows 10 April 2018 Update (version 1803)

Release date: April 30, 2018

Version 1803, called the Windows 10 April 2018 Update, is the major update to Windows 10 that preceded the October 2018 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

  • The most important new feature is Timeline, which lets you review and resume activities and open files you’ve started on your PC, or any other Windows PCs you have. It also tracks what you’ve done on iOS and Android devices if you install Microsoft’s digital assistant Cortana on them and are logged in. It shows a list of activities day by day for up to 30 days. Each activity shows up as a large tile, with the file name and document title or URL and website name across it, and the name of the application or app that created it across the top. Click any activity to reopen it. (Note that at present, Timeline only tracks activities in certain Microsoft programs such as the Edge browser and Office applications.)
  • The new Diagnostic Data Viewer is supported, which Microsoft is designed to let you see the “diagnostic data collected from your Windows devices, how it is used, and to provide you with increased control over that data.” However, the information is presented in such a complex, technical way that even programmers will likely have a difficult time understanding it. The viewer isn’t built directly into the Windows 10 April 2018 Update. Instead, you have to download it from the Microsoft Store.
  • The My People feature now lets you pin up to 10 contacts on the Windows taskbar. Previously, you could only pin up to three.
  • Microsoft Edge gets several minor tweaks, including a revamped Hub, the ability to mute auto-playing audio in tabs, and a forms-filler for web-based forms.
  • The Notebook feature of Cortana gets a new, cleaner interface for its Notebook. It now has two tabs, Organizer and Manage Skills. The Organizer makes it easier to create lists and set reminders. The Manage Skills tab lets you add “skills” to Cortana, such as controlling your home and its appliances, connecting Cortana to music services such as Spotify, tracking your fitness and more.
  • You get more control over app permissions, such as whether they can access your camera, location and contacts.

What IT needs to know: IT staff should be aware of these features that are new in the Windows 10 April 2018 Update:

  • Windows 10 Professional now gets the Windows Defender Application Guard, which protects Microsoft Edge. There’s also a new feature in the application guard that lets users download files inside Edge instead of directly to the operating system, as a way to increase security.
  • There are new policies for Group Policy and Mobile Device Management (MDM) that can better control how Delivery Optimization is used for Windows Update and Windows Store app updates. You can also now monitor Delivery Optimization using Windows Analytics.
  • Windows AutoPilot also gets a tweak that lets IT make sure policies, settings and apps are provisioned on devices before users begin using them.
  • Windows gets the Linux curl and tar utilities for downloading files and extracting .tar archives built directly into Windows. Windows also now natively supports Unix sockets (AF_UNIX) with a new afunix.sys kernel driver. That will make it easier to port software to Windows from Linux as well as from other Unix-like operating systems.
  • There are a host of improvements to the Windows Subsystem for Linux, which lets you run a variety of Linux distributions on Windows 10. Linux applications can run in the background, some launch settings for Linux distributions can be customized, and Linux applications have been given access to serial devices. The new Unix sockets report is available for the Windows Subsystem for Linux as well as Windows itself.
  • The Windows 10 Pro for Workstations version of Windows 10 gets a new power scheme called Ultimate Performance it’s only for desktop PCs, not those that can be powered by batteries. In addition, Windows 10 Pro for Workstations no longer ships with games like Candy Crush or other similar consumer-focused apps. Instead, it features enterprise- and business-related apps.
  • Administrators have been given the power to configure an enterprise’s PCs to run custom scripts during feature updates, which will make configuration and deployment easier.

For  more details, see the Microsoft blog post “Making IT simpler with a modern workplace.”

Windows 10 Fall Creators Update (version 1709)

Release date: October 17, 2017

Version 1709, called the Windows 10 Fall Creators Update, is the major update to Windows 10 that preceded the April 2018 Update. Here’s a quick summary of what’s new for users in it. (For more details, see our full review.)

  • OneDrive gets a new feature called Files On-Demand that gives you access to all of your OneDrive files on every device, without having to download them first. You’ll be able to see all the files you have in OneDrive, even if they’re only in the cloud and not on your PC. Icons tell you which are local and which are in the cloud. Just open the file, and if it’s not on your PC, it gets downloaded.
  • The new My People feature lets you pin three contacts to the Windows taskbar and then communicate with them instantly without having to open a separate app such as Skype or Mail. You can also click to see a list of all communications between them and you at a glance.
  • You can now send web links from your iOS or Android device to your PC and have them open in Microsoft Edge.
  • Cortana gets several new features, including displaying results in a scrollable flyout panel, so you don’t have to launch a web browser.
  • Microsoft Edge gets some minor improvements, including better Favorites handling and the ability to mark up PDFs and e-books.
  • Security has been beefed up, including the addition of Windows Defender Exploit Guard, which includes intrusion rules and policies to protect against a variety of threats, notably zero-day exploits. A new anti-ransomware feature called Controlled Folder Access has also been added; it lets only approved apps have access to Windows system files and folders.
  • New privacy features include the ability to review the kinds of devices and services apps from the Microsoft Store want access to before you download them.
  • The update incorporates Microsoft’s new design system and guidelines, called Fluent Design. Overall, transitions are smoother, and there are subtle changes to the transparency effect.

What IT needs to know: IT staff should be aware of these features that are new in the Windows 10 Fall Creators Update:

  • The notoriously insecure SMBv1 networking protocol, exploited in recent ransomware attacks including WannaCry and Petya, won’t be included on clean installs of the Windows 10 Fall Creators Update, but SMBv1 components will remain if you do in-place upgrades on PCs that already have the component installed.
  • Windows Defender Advanced Threat Protection (ATP), a suite of tools introduced in Windows 10 that helps enterprise customers protect their users and networks against threats and respond to attacks, is being beefed up. Among other things, it will run on the Windows Server OS.
  • ATP is also part of Windows Defender Application Guard for Microsoft Edge, available only for Windows 10 Enterprise Edition. It protects against malware attacks by confining visits to unknown or untrusted websites to a virtual machine, so that attacks can’t spread to a PC or the network.
  • Windows AutoPilot, which improves self-service deployments of Windows 10 PCs, gets a variety of tweaks, including better mobile device management (MDM) services.
  • Windows Analytics’ new Device Health tool gathers information on how PCs perform in an enterprise, and based on that, identifies potential issues and outlines steps to resolve them.
  • Enterprises get more control over what kind of information Windows Analytics gathers for the IT staff. In order to improve users’ privacy, IT staff can limit the information collected by Windows Analytics to only diagnostic data.

For more details about new features for IT, see “What’s new in Windows 10, version 1709 IT Pro content,”  “Announcing end-to-end security features in Windows 10” and “Delivering the Modern IT promise with Windows 10” from Microsoft.

Windows 10 Creators Update (version 1703)

Release date: April 5, 2017

Version 1703, dubbed the Creators Update, is the major update to Windows 10 that preceded the Fall Creators Update. Here’s a quick summary of what’s new for users in the Creators Update. (For more details, see our full review.)

  • It helps you better organize the Start menu by letting you put multiple tiles for apps into a single folder — for example, you can group all social media apps into one folder.
  • Users are given a bit more control over the update process: They can delay an update for three days and keep delaying it in three-day increments, or choose specific times for updates to install.
  • The Edge browser has gotten some improvements, including having Flash disabled by default for security reasons and supporting the ePub and PDF formats for reading books and other content.
  • Microsoft added some 3D and virtual reality features, including running HoloLens virtual reality and mixed reality apps for the first time, and introducing a Paint 3D app for creating 3D objects.
  • System settings that previously were in multiple locations have been consolidated into the Settings app.
  • There’s a new all-in-one security dashboard called Windows Defender Security Center that consolidates many security and computer health settings and information.
  • New gaming features include streaming gaming sessions over the internet; a Game Mode to improve gaming performance; and a Game bar to let you record your gameplay, take screenshots and perform games-related tasks.
  • The Cortana personal assistant gets a few modest additions, including scheduling monthly reminders and helping you set up devices.

What IT needs to know: IT staff should be aware of these features that are new in the Windows 10 Creators Update:

  • Security has been improved in a number of ways, including adding new features and insights into Windows Defender Advanced Threat Protection (ATP) to better investigate and respond to network threats. Among the new features are sensors in memory, better intelligence and improved remediation capabilities.
  • Several new configuration service providers (CSPs) available in the Creators Update let administrators manage Windows 10 devices through Mobile Device Management (MDM) or provisioning packages. The DynamicManagement CSP, for instance, can enable or disable certain device features depending on location, network presence or time.
  • New mobile application management capabilities can protect data on personal mobile devices without requiring each device to be part of the corporate MDM.
  • The Windows Configuration Designer (previously called Windows Imaging and Configuration Designer) includes new wizards to make it easier to create provisioning packages, including for desktop devices, Windows mobile devices, Surface Hub devices, HoloLens devices and kiosk devices.
  • Enterprise security administrators get a more comprehensive documentation library for Windows Defender Antivirus.
  • If an enterprise-wide update policy hasn’t been configured, users with Windows Pro, Windows Enterprise or Windows Education editions have much more control over how Windows updates. With the Creators Update, users can now automatically delay cumulative monthly updates for up to 30 days, and can delay feature updates by up to 365 days.

Windows 11 Insider Previews: What’s in the latest build?

9 June 2026 at 06:25

Windows 11 25H2 has been publicly released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out preview builds to members of its Windows Insider Program, allowing them to test out — and help shape — upcoming features.

Skip to the latest builds

Our story “How to preview and deploy Windows 10 and 11 updates” details how the Insider program has worked until now. However, Microsoft recently announced sweeping changes to the program that will include the ability to select which new features to test. As the first step, the company is introducing a new channel system and transitioning Insiders like so:

  • Beta Channel > Beta
  • Beta Channel (for devices on Windows 11 version 26H1) > Beta (26H1)
  • Dev Channel > Experimental
  • Canary Channel (28000 series) > Experimental (26H1)
  • Canary Channel (29500 series) > Experimental (Future Platforms)
  • Release Preview Channel > Release Preview 24H2/25H2
  • Release Preview Channel (for devices on Windows 11 version 26H1) > Release Preview (26H1)

This transition is happening over time, starting with the Dev Channel. See Microsoft’s blog post for more information about the transition.

Below you’ll find information about the Windows 11 preview builds that have been announced by Microsoft in the past six months. For each build, we’ve included the date of its release, which Insider channel it was released to, a summary of what’s in the build, and a link to Microsoft’s announcement about it.

Note: If you’re looking for information about updates being rolled out to all Windows 11 users, not preview builds for Windows Insiders, see “Windows 11: A guide to the updates.”

Release date: April 17, 2026

Released to: Release Preview Channel

For IT administrators, the update gradually rolls out support for a dynamic app removal list to the “Remove Default Microsoft Store packages” policy for Windows Enterprise and Education. It also removes default trust for cross‑signed third-party drivers, while drivers from the Windows Hardware Compatibility Program (WHCP) and an allow list of trusted legacy drivers remain allowed. Enterprise State Roaming can now be managed through Windows Backup for Organizations policies.

The update also immediately introduces two minor improvements for everyone. Windows quality updates now include additional high-confidence device targeting data, which increases coverage of devices eligible to automatically receive new Secure Boot certificates. In Windows Security, the name of the affected application is now included in event logging related to CVE‑2024‑30098. This change makes it easier to identify applications that rely on smart card certificates and may need updates following recent security changes.

16 ways to speed up Windows 11

5 June 2026 at 11:00

Windows 11 does a lot under the hood to speed up a PC’s performance, but PCs tend to slow down over time as they accumulate apps, files, drivers, and other detritus. Even zippy new Windows 11 devices can be sped up — and protected against future slowdowns — with a few minor system tweaks.

It’s simple to make your Windows PC run faster. Just follow these tips.

Top ways to speed up Windows 11

  1. Disable programs that run on startup
  2. Turn off unused apps with high resource usage
  3. Use Efficiency mode
  4. Use automatic Windows maintenance
  5. Kill adware and bloatware
  6. Turn off search indexing
  7. Clean out your hard drive
  8. Disable shadows, animations, and visual effects
  9. Disable transparency
  10. Change your power settings
  11. Turn off Windows tips and tricks
  12. Disable Game Mode
  13. Update device drivers
  14. Turn off background app permissions
  15. Roll back your PC to a previous state
  16. Restart Windows

Read on for details.

Note: This story covers Windows 11 version 25H2. If you have an earlier release of Windows 11, some things may be slightly different. If you have Windows 10, see our Windows 10 speed tips.

1. Disable programs that run on startup

Your Windows 11 PC could be a laggard if programs you rarely or never use are running in the background. Your PC will run faster if you stop them from running.

To do it, first launch the Task Manager in one of these ways:

  • Press Ctrl-Shift-Esc.
  • Right-click the lower-right corner of your screen and select Task Manager.
  • Type task manager into the Windows 11 search box and press Enter.

There’s a lot you can use Task Manager for, but here we’re focusing only on killing unnecessary programs that run at startup.

Click the Startup apps icon on the left side of the screen. (It’s the fifth icon from the top.) It displays a list of the programs and services that launch when you start Windows. The list includes each program’s name as well as its publisher, whether it’s enabled to run on startup, and its “Startup impact,” which is how much it slows down Windows 11 when the system starts up. Note, though, that the screen doesn’t show how much each program will impact your performance after startup, during normal PC operations.

You can use the Windows Task Manager to get information about programs that launch at startup and disable any you don’t need.

Also note that not all apps will have useful information about their startup impact — many show up as “Not measured” in Task Manager. There are multiple reasons you might see this. For example, some apps don’t provide the Windows metadata required to measure their startup impact, and others start up too late in the boot process to be measured. Still others may not have been started a sufficient number of times for Windows to measure their impact. (The Windows Club has an article with tips and workarounds for “Not measured” apps.)

To stop a program or service from launching at startup, right-click it and select Disable. This doesn’t disable the program entirely; it only prevents it from launching at startup — you can run the application after launch. Also, if you later decide you want it to launch at startup, you can return to this area of the Task Manager, right-click the application and select Enable.

Many of the programs and services that run on startup may be familiar to you, like Microsoft OneDrive or Spotify. But you may not recognize many of them. (Anyone who immediately knows what “bzbui.exe” is, please raise your hand. No fair Googling it first.)

The Task Manager can find information about unfamiliar programs. Right-click an item and select Properties for more information about it, including its location on your hard disk, whether it has a digital signature, and other information such as the version number, the file size, and the last time it was modified. (Note that not all programs provide this information when you right-click them — the Properties button may be grayed out.)

You can also right-click the item and select Open file location. That opens File Explorer and takes it to the folder where the file is located, which may give you another clue about the program’s purpose.

Finally, and most helpfully, you can select Search online after you right-click. Bing will then launch with links to sites with information about the program or service. With Task Manager’s help, I easily discovered that bzbui.exe is Backblaze backup software, something I want to run automatically during startup.

If you’re worried about one of the listed applications, you can go to a site run by Reason Software called “Should I Block It?” and search for the file name. You’ll usually find very solid information about the program or service.

Now that you’ve selected all the programs that you want to disable at startup, the next time you restart your computer, the system won’t launch those unnecessary programs automatically, and your PC may run faster.

2. Turn off unused apps with high resource usage

It’s easy to forget just how many apps you’ve got running at the same time in Windows. Sometimes your PC’s sluggishness can be due to running too many apps you’re not currently using — or a single app that’s taking up a lot of resources.

First launch Task Manager using one of the methods covered in the previous tip. If you’re already in Task Manager, click the Processes icon on the left side of the screen (three squares in a grid, second from top) to get to the Processes screen. You’ll see a list of every app or process you’re currently running.

Look for apps you’re currently running but not actively using, and also look for any not running with high memory or CPU usage. Right-click any app you want to close and select End task.

Use Task Manager to identify and shut down unused apps using lots of system resources.

3. Use Efficiency Mode

Task Manager has another trick up its sleeve for juicing Windows 11 performance. Efficiency Mode can speed up your PC and improve laptop battery life. It lowers the process priority of background applications, among other efficiency tricks.

The term is a bit of a misnomer, because you can’t put your entire PC into Efficiency Mode. Instead, you use Task Manager to put individual apps and processes into it. There’s one caveat: You’ll only be able to use it on some apps and processes.

On the Processes screen in Task Manager (see previous tip), look through the list of currently running apps and processes. Click the app or process you want to put into Efficiency Mode, click the Efficiency mode icon at the top right of the screen, and then confirm that you want to turn on Efficiency Mode for the app.

Note that if the Efficiency mode icon is grayed out when you click an app or process, you won’t be able to use it. Also, some apps, including Microsoft Edge, automatically work in Efficiency Mode by default, and the mode can’t be turned off.

4. Use automatic Windows maintenance

In the background, Windows 11 constantly performs maintenance on your PC, doing things like security scanning and performing system diagnostics to make sure everything is up to snuff. It automatically fixes problems it finds, which helps your PC run at peak performance. The automatic maintenance runs every day at 2:00 a.m. if your device is plugged into a power source and is asleep.

However, that feature may have been accidentally turned off, or it may not have run recently if you shut down your PC at night (rather than putting it in Sleep mode) or you haven’t had your laptop plugged in for a while. You should make sure it’s turned on and runs every day. You can also run it manually if you’d like.

Type control in the search box on the taskbar and select Control Panel from the results to run the Control Panel app. In the app, select System and Security > Security and Maintenance. In the Maintenance section, under Automatic Maintenance, click Start maintenance if you want it to run now.

To make sure that it runs every day, click Change maintenance settings, and on the screen that appears, select the time you’d like maintenance to run and check the box next to Allow scheduled maintenance to wake up my computer at the scheduled time. Then click OK.

Here’s how to set a time each day for Windows 11 to run its maintenance tasks.

5. Kill adware and bloatware

It may be that what’s slowing your PC down isn’t Windows 11, but bloatware or adware that takes up CPU and system resources. Adware and bloatware are particularly insidious because they may have been installed by your computer’s manufacturer. (This is generally not a problem for business PCs but is very common on consumer devices.) They typically run automatically at startup without you even knowing it. You’ll be amazed at how much better your PC will run if you get rid of it.

Start by running a system scan to find adware and malware. If you’ve already installed a security suite such as Norton Security or McAfee LiveSafe, you can use that. Microsoft Defender Antivirus, the anti-malware tool built into the Windows Security app, also does a great job. Type windows security in the search box, press Enter, and on the screen that appears, click Virus & threat protection and then click Quick scan. Windows Security will look for malware and remove any it finds.

You should get a second opinion, though, so consider a free tool like Malwarebytes. The free version scans for malware and adware and removes what it finds; the paid version offers always-on protection to stop infections in the first place.

Malwarebytes scans for and removes malware.

Preston Gralla / Foundry

Now that you’ve done all that, check for bloatware and uninstall it. A good free anti-bloatware tool is Bulk Crap Uninstaller. You can also go to the website Should I Remove It? — it offers recommendations on what software is useful, and what you can uninstall.

There’s a section of the website devoted to advice on how to remove bloatware on PCs from specific manufacturers. I highly recommend going there, because it lists all the bloatware different manufacturers install on their PCs. That section of the site also compares how much bloatware major manufacturers ship on their PCs. It rates Toshiba as having the most and Acer as having the least.

Finally, when you buy a new PC online, check whether there’s an option to leave off trial software and software you don’t need to run your PC. That will stop bloatware from getting on your system in the first place.

6. Turn off search indexing

Windows 11 search performs indexing in your hard disk in the background, allowing you to search your PC more quickly than if no indexing were being done. That’s good for fast searches, but not so good for slower PCs, because indexing can cause a performance hit. You can give a slower machine a speed boost by turning off indexing. Even if you have an SSD disk, turning off indexing can improve your speed, because the constant writing to disk that indexing does can eventually slow down SSDs.

To turn it off, type services.msc into the search box on the taskbar and press Enter. The Services app appears. Scroll down to either Indexing Service or Windows Search in the list of services. Double-click it, and on the screen that appears, click Stop. Then reboot your machine. Your searches may be slightly slower, but you also may not notice the difference. You should, though, get an overall speed boost.

turning off windows indexing

Here’s how to turn off Windows 11 indexing.

Alternatively, you can turn off indexing only for files in certain locations. In this way, you can still index files and folders you often search for but turn off indexing for the rest of your hard disk. So you’d still get fast searches for files you use often, while increasing your PC’s performance.

To do it, type index in the Windows 11 search box and click the Indexing Options result that appears. The Indexing Options page of the Control Panel appears. Click the Modify button, and you’ll see a list of locations that are being indexed, such as Microsoft Outlook, your personal files, and so on. Uncheck the box next to any location, and it will no longer be indexed.

7. Clean out your hard drive

A bloated hard drive filled with files you don’t need can slow down your PC. Taking a few minutes to clean it can give an immediate speed boost. A built-in Windows 11 tool called Storage Sense will do the job for you.

Launch the Settings app, select System > Storage, scroll down to the “Storage management” section, and next to Storage Sense, move the toggle from Off to On. From now on, Windows will constantly monitor your PC and delete old junk files you no longer need — temporary files, files in the Downloads folder that haven’t been changed in a month, and old Recycle Bin files.

screenshot of windows settings  /> system > storage screen with storage sense toggle highlighted

Here’s where to turn on Storage Sense.

Preston Gralla / Foundry

You can also customize when Storage Sense runs and what should be deleted automatically — for example, whether to delete files from the Downloads folder after they’ve been there for more than 30 days. To do it, click the right-facing arrow next to the Storage Sense On/Off slider.

8. Disable shadows, animations, and visual effects

Those who like eye candy are probably big fans of Windows 11’s shadows, animations, and visual effects. They typically don’t affect performance on fast, newer PCs. But they can exact a performance hit on older, slower machines.

If you’ve got a slower PC, turn them off. To do it, in the Windows 11 search box, type sysdm.cpl, press Enter, and then click the sysdm.cpl icon. That launches the Control Panel’s System Properties dialog box. Click the Advanced tab and click Settings in the Performance section. That brings you to the Performance Options dialog box. (Make sure you’re on the Visual Effects tab of the dialog box.) You’ll see a varied list of animations and special effects.

performance options dialog box listing animations and other options to turn off for faster performance

The Performance Options dialog box lets you turn off visual effects that might be slowing down Windows 11.

Preston Gralla / Foundry

If you love to tweak, you can turn individual options on and off. These are the animations and special effects you’ll probably want to turn off, because they have the greatest effect on system performance:

  • Animate controls and elements inside windows
  • Animate windows when minimizing and maximizing
  • Animations in the taskbar
  • Fade or slide menus into view
  • Fade or slide ToolTips into view
  • Fade out menu items after clicking
  • Show shadows under windows

However, it’s a lot easier to just select the Adjust for best performance option at the top of the screen and click OK. Windows 11 will then turn off the effects that slow down your system.

9. Disable transparency

To get an even bigger speed boost, go beyond turning off shadows, animations, and visual effects. Also disable the transparency effects in the taskbar and other Windows 11 locations. Windows does a surprising amount of heavy lifting to create transparency effects, and turning them off can make a difference in system performance.

To do it, run the Settings app and select Personalization > Colors, then move the Transparency effects slider to Off.

screenshot of windows settings  /> personalization > colors screen with transparency effects toggle highlighted

Turning off Windows 11’s transparency effects can help speed up performance.

Preston Gralla / Foundry

10. Change your power settings

Your Windows 11 PC’s power settings let you balance its energy use with its performance. If you’re using the most power-efficient setting, you’re slowing down your PC, because the setting reduces your PC’s performance to save energy. (Even desktop PCs typically have a power-saving setting.) Changing your power setting to one of the less power-efficient options will give you an instant performance boost.

To do it, run the Settings app, then choose System and click the right-facing arrow next to Power. Depending on whether you’re using a laptop or a desktop PC (and if you’re using a laptop, whether it’s plugged in), you’ll see either a “Plugged in” or “On battery” setting that lists the power mode you’re using. Click the drop-down arrow next to it and choose the setting you want.

Change your power settings to give your PC a performance boost.

Preston Gralla / Foundry

Best Performance gives you the most oomph but uses the most power. Balanced finds a happy medium between power use and better performance, and Best Power Efficiency does everything it can to give you as much battery life as possible. Desktop users have no reason to choose Best Power Efficiency, and even laptop users should consider the Balanced option when unplugged.

11. Turn off Windows tips and tricks

Windows 11 constantly watches what you’re doing on your PC and gives you tips about things you might want to do with the operating system. I’ve never found these tips helpful. And I don’t like the privacy implications of Windows constantly taking a virtual look over my shoulder. (Also see: How to protect your privacy in Windows 11.)

Beyond that, this monitoring can also make your PC run more sluggishly. So to speed things up, tell Windows to stop being so nosy and giving you advice. To do it, run the Settings app and select System > Notifications. Scroll down to Additional settings and click the down arrow. From the options that appear, uncheck the box marked Get tips and suggestions when using Windows.

screenshot of Windows notifications additional settings with windows tips checkbox

Turn off Windows’ suggestions to help things run more smoothly (and regain a measure of privacy).

Preston Gralla / Foundry

12. Disable Game Mode

Windows 11’s Game Mode optimizes your PC for playing games. When it detects that you’re playing a game, it prioritizes system resources for gaming, taking them away from other apps and background processes. That’s great for serious gamers, but when you’re not playing games, it can slow down your system because it keeps some system resources in reserve in case you start playing a game. It occasionally causes stability issues as well. So turning off Game Mode may be able to give your PC a quick boost. (You can always turn it back on again when you want to play a game.)

Game Mode is turned on by default, so even if you’ve never played a game on your PC, it’s probably enabled. To turn it off, go to Settings > Gaming > Game Mode and move the Game Mode slider to Off.

screenshot of windows settings  /> gaming screen with game mode area highlighted

Game Mode can sometimes cause stability and performance issues, so turning it off may give your PC a boost.

Preston Gralla / Foundry

13. Update device drivers

Your Windows 11 PC can become a slowpoke if its drivers are old and in the way. Outdated drivers can exact a big performance hit. Graphics drivers are often the biggest culprit in driver-related slowdowns. To check whether your graphics driver is outdated, and to update to the latest one:

  1. In the Windows search box, type device manager and click on the Device Manager icon that appears.
  2. Scroll to the Display Adapters entry and click the side-facing arrow to expand it.
  3. Right-click the driver, and from the context menu that appears, select Update Driver.

You’ll be asked whether to have Windows search for an updated driver, or whether you want to find one and install it manually. Your best bet is to let Windows do the work. Follow the on-screen instructions to get the driver installed.

You can use the Device Manager to update all your drivers this way. That’s time-consuming, so consider asking Windows to do the work for you. To do it, launch the Settings app (pressing the Windows key + I is a good shortcut for doing it) and select Windows Update from the left pane.  Select Advanced Options > Optional Updates. You’ll see a list of all the updates Windows has found but hasn’t installed. Select any of the drivers you want to install, then click Download & install.

Tell Windows Update to update your drivers.

14. Turn off background app permissions

Some apps run various processes in the background even if you don’ t launch them. You’ll likely never know they’re doing it, and they can cause unexpected slowdowns and a sluggish PC. Microsoft says these background processes do things such as syncing or sending notifications. That can slow your PC down, especially if more than one app is doing it.

You can head off performance problems by not allowing the apps to run in the background. To do it:

  1. Go to Settings > Apps > Installed apps.
  2. Click the three horizontal dots on the right of any app whose permissions you want to turn off and select Advanced options.
  3. Click the dropdown under “Background app permissions,” and choose Never if you want to stop the app from ever running a process in the background, or Power optimized if you want to let Windows decide whether to let the processes run when they won’t cause your PC to take a performance hit.
screenshot of settings  /> apps > installed apps > claude with background app permissions dropdown menu

Managing background app permissions properly can give your PC a performance boost.

15. Roll back your PC to a previous state

Sometimes your PC will slow down for no apparent reason, and stay slow. It could be a new driver slowing your system down. Perhaps accidentally you changed a system setting that caused the problem. It can be difficult, and often impossible, to get to the root of these kinds of problems and fix them.

If you’ve noticed that your computer has become sluggish recently, there’s something that might solve the issue: Restore your PC to the state it was in before the problem began. You can easily do this via System Restore.

To do it:

  1. Make sure System Restore is turned on by going to Settings > System > About, and under the “Device info” section, click System protection.
  2. From the screen that appears, click Configure and select Turn on system protection if it’s not already turned on. Click OK.
  3. You’ll be sent back to the System Protection screen. Click System Restore.
  4. On the screen that appears, select Recommended restore and click Next if you want to revert to the most recent restore point. Select Choose a different restore point if you want to choose one yourself, and click Next.
  5. Restart your PC. It will revert to its previous state. Note that when you do this, your documents, pictures, and personal data won’t be deleted.

Here’s how to turn on System Restore.

16. Restart Windows

Here’s one of IT’s not-quite-secret weapons for troubleshooting and speeding up a PC: shut it down and restart it. Doing that clears out any excess use of RAM that otherwise can’t be cleared. It also kills processes that you might have set in motion and are no longer needed, but that continue running and slow your system.

If your Windows 11 PC has turned sluggish over time for no apparent reason, you may be surprised at how much more quickly it will run when you do this. I can vouch for it, and I restart my Windows 11 PCs regularly even if they’re not sluggish, just as a precautionary measure.

Windows 11 Insider Previews: What’s in the latest build?

1 June 2026 at 06:20

Windows 11 25H2 has been publicly released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out preview builds to members of its Windows Insider Program, allowing them to test out — and help shape — upcoming features.

Skip to the latest builds

Our story “How to preview and deploy Windows 10 and 11 updates” details how the Insider program has worked until now. However, Microsoft recently announced sweeping changes to the program that will include the ability to select which new features to test. As the first step, the company is introducing a new channel system and transitioning Insiders like so:

  • Beta Channel > Beta 
  • Dev Channel > Experimental

How to protect Windows 10 and 11 PCs from ransomware

29 May 2026 at 07:00

CryptoLocker. WannaCry. DarkSide. Conti. MedusaLocker. Qilin. The ransomware threat has exploded over the past decade, and it isn’t going away anytime soon; the news brings constant reports of new waves of this pernicious type of malware washing across the world.

Ransomware gained in popularity in large part because of the immediate financial payoff for attackers: It works by encrypting the files on your hard disk, then demanding that you pay a ransom, frequently in Bitcoin or other cryptocurrency, to decrypt them. Now many ransomware gangs are switching tactics, stealthily infiltrating enterprise systems, collecting sensitive corporate data over time, and later threatening to expose that data if the organization doesn’t pay up.

Nevertheless, individuals and businesses are still at risk from traditional ransomware attacks. In this article, I’ll show you how to keep yourself safe in Windows 11 — and Windows 10 too, for those who haven’t yet moved to Windows 11 — including how to use an anti-ransomware tool built into both versions of Windows.

(Administrators, see “What IT needs to know about ransomware and Windows” at the end of this article.)

This article assumes that you’re already taking the basic precautions against malware in general, including running anti-malware software and never downloading attachments or clicking links in email from unknown senders and suspicious-looking email. Also note that this article has been updated for Windows 11 25H2 and Windows 10 22H2. If you have an earlier Windows release, some things may be different.

Use controlled folder access

Microsoft is concerned enough about ransomware that it built an easy-to-configure anti-ransomware tool directly into Windows 10 and 11. Called controlled folder access, it protects you by letting only safe and fully vetted applications access your files. Unknown applications or known malware threats aren’t allowed through.

By default, the feature is not turned on, so if you want to protect yourself against ransomware, you’ll have to tell it to get to work. And you can customize exactly how it works by adding new applications to its whitelist of programs that can access files, and adding new folders in addition to the ones that it protects by default.

To switch it on, you’ll need to access Windows Security. To get to it in Windows 11, click Start > Settings to open the Settings app, then select Privacy & Security > Windows Security.  

In Windows 10, click Start > Settings to open the Settings app, then select Update & Security > Windows Security.

In Windows Security, select Virus & threat protection. On the screen that appears, scroll down to the “Ransomware protection” section and click Manage ransomware protection. On the next screen, under “Controlled folder access,” toggle the switch to On. You’ll get a prompt asking if you want to make the change. Click Yes.

Switch the toggle to On to turn on controlled folder access.

You shouldn’t leave it at that and feel safe yet, because there’s a chance that you have folders you’d like to protect that the feature ignores. By default, it protects Windows system folders (and folders underneath them) like C:\Users\UserName\Documents, where UserName is your Windows user name. In addition to Documents, Windows system folders include Desktop, Music, Pictures, and Videos.

But all your other folders are fair game for any ransomware that makes its way onto your PC.

To add folders you want protected, click the Protected folders link that appears after you switch on controlled folder access. A prompt appears asking if you want to make the change. Click Yes. Click the Add a protected folder button that is on top of the list of protected folders that appears, then navigate from the screen that appears to the folder you want to protect and click Select Folder.

protected folders list in windows 11 security settings

Click Add a protected folder to protect more of your folders with controlled folder access.

Preston Gralla / Foundry

Continue to add folders in this way. Remember that when you add a folder, all folders underneath it are protected as well.

If you decide at any point to remove a folder, get back to the “Protected folders” screen, click the folder you want to remove, and then click Remove. Note that you won’t be able to remove any of the Windows system folders that are protected when you turn the feature on. You can only remove the ones that you’ve added.

Microsoft determines which applications should be allowed access to protected folders, and unsurprisingly, among them are its own Microsoft Office apps. Microsoft hasn’t published a list of which apps are allowed, though, so consider taking action to let apps you trust access your files.

To do it, go back to the screen where you turned on controlled folder access and click Allow an app through Controlled folder access. A prompt appears asking if you want to make the change. Click Yes. From the screen that appears, click Add an allowed app, navigate to the executable file of the program you want to add, click Open, and then confirm you want to add the file. As with adding folders to the list of protected folders, you can remove the app by getting back to this screen, clicking the application you want to remove, then clicking Remove.

Hint: If you’re not sure where executable files are located for programs you want to add to the allow list, look for the folder name with the program’s name in the “WindowsProgram Files” or “WindowsProgram Files (x86)” folders, then look for an executable file in that folder.

Note: In Windows 11, OneDrive folders are automatically protected by controlled folder access when you turn it on. However, they may not necessarily be protected in Windows 10. In Windows 10, on the “Ransomware protection” page, you’ll be notified in the Ransomware data recovery section whether your OneDrive files are protected. If they’re not protected, click the Set up OneDrive button there.

Back up… but do it properly

The whole point of ransomware is to hold your files hostage until you pay to unlock them. So one of the best protections from ransomware is to back up your files. That way, there’s no need to pay the ransom, because you can easily restore your files from the backup.

It’s a good idea to not just back up to a local drive but additionally use a reputable cloud-based storage and backup service. If you back up to a drive attached to your PC, when your PC gets infected with ransomware, the backup drive will likely be encrypted along with any other disks inside or attached to your PC. Cloud backups are generally less vulnerable but not wholly immune to ransomware attacks.

Make sure that your backup service uses versioning — that is, it keeps not just the current version of each of your files, but previous ones as well. That way, if the most current version of your files gets infected, you can restore from previous versions. Most popular backup and storage services, including Microsoft OneDrive, Google Drive, Carbonite, Dropbox, and many others, use versioning. It’s a good idea to get familiar with the versioning feature of whichever service you use now, so you can easily restore files in a pinch.

Some services, including OneDrive and Google Drive, now offer ransomware detection. Users are notified of suspicious activity and can use the vendors’ tools to remove infected files and restore older versions.

Stay patched

Microsoft regularly releases Windows 10 and Windows 11 security patches, and they’re automatically applied via Windows Update. But if you hear about a ransomware outbreak, you shouldn’t wait for Windows Update to work — you should immediately get the update yourself so that you’re protected as soon as possible. And it’s not just Windows updates you want to get. You also want to make sure Windows Security, Microsoft’s built-in anti-malware tool, has the latest anti-malware definitions.

To do both in Windows 10, go to Settings > Update & Security > Windows Update and click the Check for updates button. In Windows 11, go to Settings > Windows Update and click the Check for updates button. (If updates are already waiting for you, you’ll see them listed instead of the Check for updates button.) If Windows finds updates, it installs them. If it requires a reboot, it will tell you.

Preston Gralla / Foundry

You need to worry not just about Windows staying patched, but other software as well. If you use an anti-malware program other than Windows Security, make sure it and its malware definitions are up to date.

And the other software on your PC should be kept up to date as well. So check how each piece of software gets updated and make sure to update each one regularly. For help keeping all your apps up to date, consider setting up an automated tool like Patch My PC Updater or Software Update Monitor (see our tutorial “How to keep your apps up to date in Windows 10 and 11”) — or, if you’re comfortable using the command line, try the WinGet command (see “WinGet: The best way to keep Windows apps updated”).

Disable macros in Microsoft Office

Ransomware can be spread via macros in Office files, so to be safe you should turn them off. Microsoft now disables macros from the internet by default, but that doesn’t necessarily mean that they’re turned off in your version of Office, depending on when you installed it and whether you’ve updated it.

To turn them off, when you’re in an Office application, select File > Options > Trust Center > Trust Center Settings and select either Disable all macros with notification or Disable all macros without notification. If you disable them with notification, when you open the file you’ll get a message warning that the macros were disabled and letting you turn them on. Only turn them on if you’re absolutely sure they’re from a safe, trusted source.

Here’s how to disable macros in Office.

Get ransomware protection and/or mitigation tools

Just about any anti-malware program includes built-in anti-ransomware protections, but there are several programs that promise to specifically target ransomware. Most are paid, but there are also some free options.

Bitdefender offers free decryption tools that can unlock your data if you’ve been attacked by ransomware and it’s being held ransom. They can only decrypt data that’s been encrypted with certain specific pieces or families of ransomware, including REvil/Sodinokibi, DarkSide, MaMoCrypt, WannaRen, and several others. Avast offers its own set of free decryption tools.

What IT needs to know about ransomware and Windows

Many Microsoft 365 and Windows commercial plans, especially at the enterprise level, include ransomware detection and protection tools. Advanced products such as Microsoft Defender XDR are also available under separate licenses.

Even without those tools, there’s plenty that admins can do to protect Windows systems from ransomware. The most obvious: Apply the latest security patches to not just all PCs in an organization, but all servers and any other enterprise-level hardware. Also lock down application permissions, train users to spot phishing attempts, and, of course, securely back up all corporate data.

IT also needs to make sure the notoriously insecure SMB1 Windows networking protocol is disabled in all devices. Multiple ransomware attacks have spread through the 30-year-old protocol; even Microsoft says it should be used by no one, ever.

The good news is that Windows 10 version 1709, released in October 2017, finally did away with SMB1. (It’s not in Windows 11, either.) But that’s only for PCs with clean installs of version 1709 or later. Older PCs that were updated from earlier versions of Windows still have the protocol built in.

The Microsoft support article “Detect, enable and disable SMBv1, SMBv2, and SMBv3 in Windows” offers details about how to turn off the protocol. It recommends killing SMB1 but keeping SMB2 and SMB3 active, and only deactivating them for temporary troubleshooting.

Administrators can use the controlled folder access feature (covered earlier in this article) to stop ransomware from encrypting files and folders of PCs running Windows 11 or Windows 10 version 1709 or later. They can use the Group Policy Management Console, the Windows Security Center, or PowerShell to turn on controlled folder access for users on a network, customize which folders should be protected, and let additional applications access the folders beyond the Microsoft defaults, as detailed  in the Microsoft articles “Enable controlled folder access” and “Customize controlled folder access.”

One potential issue with controlled folder access is that it might block apps that users typically use from accessing folders. So Microsoft recommends using audit mode first, to see what will happen when controlled folder access is turned on. For information about how to do it, go to Microsoft’s “Evaluate exploit protection” documentation.

As noted above, Office macros can spread ransomware. Microsoft is now blocking macros downloaded from the internet by default, but to be safe, IT should use Group Policy to block them. For advice on how to do it, go to the “Block macros from running in Office files from the Internet” section on Microsoft’s “Macros from the internet will be blocked by default in Office” documentation.

Windows 11: A guide to the updates

27 May 2026 at 06:45

A Windows launch isn’t the end a process — it’s really just the beginning. Microsoft continually works on improving Windows 11 by fixing bugs, releasing security patches, and occasionally adding new features.

In this story we summarize what you need to know about each update released to the public for the most recent version of Windows 11 — currently version 25H2 — over the past year. For each build, we’ve included the date of its release and a link to Microsoft’s announcement about it. The most recent updates appear first.

The easiest way to install updates is via Windows Update. Not sure how? See “How to handle Windows 10 and 11 updates” for full instructions. Note that Windows 11 version 25H2 is being released as a phased rollout and may not be available to you in Windows Update yet.

If you’re still using Windows 10, see “Windows 10: A guide to the updates.” And if you’re looking for information about Insider Program previews for upcoming feature releases of Windows 11, see “Windows 11 Insider Previews: What’s in the latest build?”

Updates for Windows 11 25H2 and 24H2

KB5089573 (OS Builds 26200.8524 and 26100.8524) Preview

Release date: May 26, 2026

With this update, Windows quality updates include additional high-confidence device targeting data, making more devices eligible to receive new Secure Boot certificates. The old certificates expire at the end of June: see Computerworld’s FAQ for details. The build also adds Group Policy and MDM settings that IT admins can enable to limit the Secure Boot service data sent to Microsoft. (See Microsoft documentation.)

This update also includes a wide variety of new features being rolled out gradually, including Shared Audio, which enables two Bluetooth audio devices to connect to a single Windows 11 PC at the same time; Multi-App Camera, which allows multiple applications to access the camera stream simultaneously; improved visibility into NPU usage in Task Manager; and several performance and behavior improvements for Windows Hello.

There is one known issue in the update, in which after you install update KB5089549, some devices might fail to complete installation with error code 0x800f0922. This issue occurs on devices that have limited free space on the EFI System Partition (ESP), especially if it has 10MB or less available.

(Get more info about KB5089573 Preview, including workarounds for the issue described above.)

KB5089549 (OS Builds 26200.8457 and 26100.8457)

Release date: May 12, 2026

This build enables dynamic status reporting for Secure Boot states in the Windows Security app. It also fixes a bug in which the Remote Desktop Connection security warning dialog sometimes rendered incorrectly in multi-monitor configurations with different display scaling settings.

Windows 11 25H2

At the end of September, Microsoft upgraded Windows 11 from version 24H2 to 25H2, in a slow rollout that could take months to complete. Typically in the past, Microsoft would introduce new features in a once-a-year update like this. That’s not the case with 25H2, though.

Microsoft has been introducing new features in smaller updates all year round, so 25H2 doesn’t include any major new features. Rather, it includes all the new features that have accumulated in all those smaller updates.

As the company explains, “While this update doesn’t introduce major new features, it activates enhancements that have been gradually rolled out over the past year ensuring your device is up to date with the latest refinements.”

Here are some of the most important features in 25H2 that have been introduced for end users and IT pros since 24H2 was released last fall:

New features for users:

  • File Explorer has several useful new features, notably AI actions, which can edit images or summarize documents. AI options such as Blur background, Erase objects, and Remove background are all now displayed in the context menu.
  • Task Manager gets a number of minor tweaks, including performance improvements when changing the sort order of processes.
  • You can now display the apps that have recently used on-device generative AI models provided by Windows. You can also choose which apps are permitted to use the generative AI technologies. To do that and more, go to Settings > Privacy & security > Text and Image Generation.

New features for IT:

  • IT admins can use policy-based tools to easily remove preinstalled Microsoft Store apps from Enterprise and Education editions of Windows 11, version 25H2 and later. This can streamline device provisioning and prevent removed apps such as Microsoft Clipchamp, Media Player, and Microsoft Teams from being reinstalled. For more information, see Policy-based removal of preinstalled Microsoft Store apps and RemoveDefaultMicrosoftStorePackages in the ApplicationManagement Policy CSP.
  • Enterprise access points now support Wi-Fi 7, which enables increased speeds, greater throughput, improved reliability, and enhanced security. For details, see https://aka.ms/WiFi7forEnterprise.
  • Windows Backup for Organizations is now generally available.
  • A new feature called Quick Machine Recovery can recover Windows devices when they encounter critical errors that prevent them from booting. Quick machine recovery searches for remediations in the cloud and recovers from widespread boot failures, reducing the burden on IT admins on cases when multiple devices are affected. For more information, see Computerworld’s Quick Machine Recovery explainer.

Updates for Windows 11 24H2

KB5068221 (OS Build 26100.6588) Out-of-band

Release date: September 22, 2025

This update fixes a bug that affected Microsoft Office applications running in Microsoft Application Virtualization (App-V) environments. The failure occurred due to a double handle closure in the AppVEntSubsystems32 or AppVEntSubsystems64 system component.

There is one issue in this build: you might fail to connect to shared files and folders using the Server Message Block (SMB) v1 protocol on NetBIOS over TCP/IP (NetBT). This issue can occur if either the SMB client or the SMB server has the September 2025 security update installed.

(Get more info about KB5068221 (OS Build 26100.6588) Out-of-band).

The agent uses AI on your PC to understand your request and, with your permission, can automate and complete tasks for you. It is rolling out to Snapdragon-powered Copilot+ PCs now, with support for AMD and Intel PCs coming soon. 

Several bugs have also been fixed, including one in which If you have an app pinned to your desktop and it updates, the app icon might not display correctly and instead show a white page.

KB5061977 (OS Build 26100.4066) 

Release date: May 27, 2025

This out-of-band update fixes a bug in the direct send path for a guest physical address (GPA). This issue caused confidential virtual machines running on Hyper-V with Windows Server 2022 to intermittently stop responding or restart unexpectedly. As a result, service availability was affected, and manual intervention was required. This problem primarily impacted Azure confidential VMs.

KB5055627 (OS Build 26100.3915) Preview

Release date: April 25, 2025

This build gradually rolls out several new features for Copilot+ PCs, including a preview of Windows Recall. When you opt in, Recall takes snapshots of your activity so you can quickly find and go back to what you have seen before on your PC. With it, you can use a timeline to find the content you remember seeing.

Copilot+ PCs also get a new natural-language Windows search in which you can search for anything on your PC without having to remember specific file names, exact words in file content, or settings names. Just describe what you’re looking for. On Copilot+ PCs, you can also more easily find photos stored and saved in the cloud by typing your own words (like “summer picnics”) in the search box at the upper-right corner of File Explorer. 

All PCs get a number of new features, including speech recap, in which you can keep track of what Narrator has spoken and access it for quick reference. With speech recap, you can quickly access spoken content, follow along with live transcription, and copy what Narrator last said using keyboard shortcuts.

A variety of bugs are being fixed, including one in which some devices experienced intermittent internet connections when resuming from sleep mode. Several AI components have also been updated.

There are two known issues in this build, including one in which players on Arm devices are unable to download and play Roblox from the Microsoft Store on Windows.
