AI agents are performing roughly 1 in 3 actions in enterprise IT workflows (but that share is rising quickly), while human analysts are rejecting about one-quarter of AI-proposed actions (but that rate is falling), according to a new study of tens of thousands of human-AI interactions. Operational data, rather than underlying AI infrastructures, is often the culprit when things go wrong.

Human analysts are approving the most consequential actions, managing exceptions, and supervising and shaping agentic systems, while AI agents are carrying out routine tasks and executions, automation platform provider Fixify found in the study.

“That may sound less dramatic than replacing the help desk,” Matt Peters, Fixify’s co-founder and CEO, wrote in a blog post. “It’s also a much more credible path to changing how IT work gets done.”

Building scaffolding

Fixify identified four steps of agentic work: Planning, proposing, approving or declining, then acting on approved steps.

It analyzed nearly 18,000 plans and over 147,000 actions executed by agents across 40 companies over a three-month period, finding that agents are taking over one-third of IT actions, most notably in software, applications, security, and collaboration work where requests tend to be “repeatable and easy to reverse.”

Tasks that are well understood and that present low risk are best suited for the current generation of agents, Peters wrote. Human analysts remain closely involved in higher-stakes areas like identity verification, setting up and removing IT access (onboarding and offboarding), and hardware environments.

However, AI’s share of the work is increasing as feedback loops improve: Over the three-month period, human approval of AI-proposed actions rose from 23% to 41%, and rejection fell from 27% to 16%, Fixify found.

The company identified six types of actions in AI automation. Running a skill — actually doing something — accounted for 39.4% of all actions). Most of the rest were coordination: sending a message to the human requester (27.7% of actions), leaving an initial comment (13.2%), giving instructions to a human analyst (9.8%), or waiting (8.8%). Running entire workflows accounted for just 1.1% of actions.

AI is building “scaffolding” that wraps around meaningful changes, often planning far more scenarios than the agent will execute. Typically, agents map out 15 possible actions but run only two, Fixify said.

“The agent maps the paths a request could take, then walks down the path that makes the most sense as it meets reality,” the study said.

Peters pointed to one example where an AI agent identified which team needed access to process a high-volume type of ticket. Rather than fully automating the process, the agent did the initial triage, asked questions, then routed tickets to the team that had the information to act immediately.

“We didn’t need a world-ending hive mind,” he said. “We just needed to point a little conversational intelligence in the right direction.”

When AI breaks down

IT automation typically involves analyzing tickets and moving them along; in other words, low-risk tasks.

But agents do participate in areas like security (albeit only about 6%), most notably adding and removing people from groups or channels, unlocking accounts, resetting passwords, analyzing multi-factor authentication (MFA), provisioning (or deprovisioning) accounts, and assigning software licenses.

However, this identity-lifecycle work is where agents failed the most, particularly in onboarding and offboarding and identity-access management (IAM), the study found. “Hardware and connectivity changes rarely fail; identity-lifecycle changes fail three-to-nine times as often.”

Why AI breaks down

Thanks to human-in-the-loop controls, Fixify was able to analyze scenarios where agent recommendation diverged from human judgment. This occurred about 23% of the time.

The largest failure category (nearly 50%) was ‘target not found,’ meaning the agent couldn’t uncover what it needed. This typically comes down to poor data: A user, group, account, or resource was not where the system expected it to be. When people change teams, groups are restructured, accounts are renamed, or work has already been done but not reflected in the system, this is more of an identity hygiene problem than an AI problem. The system needs cleaner and more current data.

Invalid inputs accounted for around 29% of failures, followed by unhandled errors, denied permissions, or invalid operations or configurations. The latter signal “real breakage” in integrations, according to Fixify.

AI becomes more sophisticated over time

The good news is that AI automation improves over time, even if it might take a while. In hybrid systems, humans keep the most consequential changes under their own control, and iterative rejection and approval helps AI learn.

Over time, agents’ plans get leaner and they start to re-plan when conditions change, rather than pre-planning all kinds of scenarios that may never occur. “That’s a sign of sophistication,” the study said. “Adapting in the moment is a more advanced behavior than trying to pre-script every contingency.”

In turn, humans second guess the system less often and feel comfortable handing off more work. Instead, they control how agents behave, make high-impact decisions, and handle exceptions. “The hardest requests remain human-heavy, especially those that require repeated replanning or contextual judgment,” the study said.

How teams can adapt to AI agents

As agentic AI becomes embedded in more workflows — and at deeper levels — enterprises must evolve to accommodate, Fixify emphasized.

This means investing in clean identity data and building strong playbooks, review workflows, and reliable integrations.

Teams should judge agentic tools by their supervision loop and view rejections as a training process, Fixify advised. Analyst time, queues, and metrics should be built around reviewing proposals. Agent replanning can be seen as a routing signal: A single replan might indicate healthy adaptation, while repeated replanning means ambiguity, irrelevance, or unclear policies.

“Make the review surface easy to understand so analysts can assess proposed actions and make quick decisions about how to proceed,” the study advised. “This is where the analyst’s attention belongs.”

Now that Samsung has jumped into the crowded AI-powered glasses arena alongside Apple, Google, Meta, and others, CISOs and IT leaders are again having to think through whether it makes sense to establish enterprise restrictions on such devices, given the likely data leakage and privacy and compliance issues.

And even if those tech leaders decide that such policies might make sense, the logistical hurdles to universally enforcing them outside the office are all but insurmountable.

For example, it is up to individual wearers to choose their device’s settings, making it difficult for IT policies around data acquisition and usage to be enforced. Worse, AI devices have a history of ignoring guardrails. That means that a setting that limits how data is used may not necessarily be obeyed. 

One possible mitigating factor is that smart glasses typically have a light on the frame that activates when the device is recording, but there are also many easy ways for workers to defeat or cover up those lights to conceal their activities. 

Enforcement is virtually impossible

However, said independent technology analyst Carmi Levy, “although some organizations have tried to physically ban smart glasses from their in-person and virtual workplaces, the sad reality for corporate technological gatekeepers is there is no way to completely keep any device out of the workplace.”

There is nothing stopping employees from wearing eyewear of any type, smart or not, he noted, “and attempting to do so might put employers on the wrong side of a disability lawsuit launched by a worker who needs prescription smart glasses to accommodate vision issues.”

As well, Jitesh Ubrani, an IDC director focusing on worldwide device trackers, pointed out that the biggest challenge in creating rules around usage of smart glasses is that the data leakage problem with devices is both not new and certainly not limited to glasses. 

“The instinct to ban AI smart glasses outright is understandable, but it misses that the underlying risk isn’t new. A smartphone has been able to record a whiteboard, a screen, or a conversation for close to two decades,” he said. “What’s changed is the friction. Glasses make covert capture nearly effortless and far harder to notice because there’s no phone being visibly raised or pointed. That’s a real escalation in ease of misuse, but it’s a difference of degree rather than a fundamentally new capability.”

In fact, Ubrani argued, “where this gets hard for CISOs is enforcement. A ban on paper is easy to write. Enforcing it inside a corporate office is already difficult, since most current-generation devices, including Meta’s Ray-Bans, are visually indistinguishable from ordinary eyewear.”

And, he added, “enforcing it in a hybrid or work-from-home setting is close to impossible. IT has no practical way to confirm what someone is wearing on a home Zoom call, and even in-office detection options, like scanning for Bluetooth or BLE advertising signals tied to known manufacturer IDs, only catch devices that haven’t been reconfigured or that happen to be broadcasting at the time.”

Additional risk

Connected glasses have a history going back decades, but enterprises didn’t take them seriously until this year.

But Anshel Sag, principal analyst at Moor Insights & Strategy, characterized the problem as more psychological than technological. 

“People want to ban it because they don’t know how to handle it. But that just creates more problems than it solves. It’s a very kneejerk fear reaction,” Sag said. “We live in an era where cameras are everywhere.”

Meghan Hollis, a senior principal analyst for Gartner, agreed that the focus on smart glasses is misplaced, given that even headphones can today capture audio for translation and transcription. The change is not in the data capture, Hollis said, but the fact that it is adding video.

This creates additional risk, with the new capability brought into the corporate environment causing “a potential exposure for corporate intellectual property,” Hollis said.

One other often-overlooked issue is data sovereignty. Even if the glasses manufacturer agrees to store data only in specific countries, it could easily change that policy or simply switch third-party vendors. 

“There could be export control issues, possibly violating regulatory controls in transmitting information,” Hollis noted. 

However, Hollis said, threatening to punish workers if they are caught using unauthorized devices “is your last line of defense,” and that the best initial approach should not be enforcement, but education.

“You need to be educating your end-users, with constant reinforcement, telling them, ‘If you do this, here’s how you can harm the company and our clients/customers.’ Combine that with, ‘And if you do this, we will take action against you.’”

Tiered policies required

Hollis noted that the risk goes beyond an employee initially recording something they shouldn’t. Consider, for example, a technical meeting where an employee asks the rest of the attendees for permission to record the discussion. They agree and he starts to record. 

At the end of the meeting, he leaves to return to his office, fully intending to turn off the recording function when he gets there. But on the way, he has a brief hallway meeting with an SVP who tells him, without warning, “FYI, but the board just decided to greenlight our hostile takeover of Smith Corp. We’ll explore the specifics at a 10 a.m. tomorrow. Have your team there.” The executive then walks off.

With the recording still running, that ultra-sensitive data has just been transmitted to the cloud. 

IDC’s Ubrani pointed out that situations like this make smart glasses governance more challenging. “Enterprise IT and security leaders need to stop framing this as ‘ban versus allow,’ and instead build a tiered policy based on where the actual risk sits,” he said. “Boardrooms, R&D labs, and any space where trade secrets or regulated data are visible or discussed out loud deserve strict no-wearables rules, enforced the same way phone bans already are in those rooms.”

Open floor plans and general office space probably don’t need that level of restriction, he said, but meeting policies should require disclosure when a device capable of recording is present, similar to the way in which some companies already handle personal recording devices in sensitive briefings.

“Companies that try to write one blanket rule for every environment are going to find it’s either unenforceable or so restrictive it interferes with accessibility, since some employees rely on these devices as assistive technology,” he said.

However, Brian Jackson, a principal research director at Info-Tech Research Group, argued that enterprise CISOs and IT Directors need to take a far more strict position.

“Organizations should update their acceptable use policies for personal technology ASAP,” he said. “Look back about 15 years ago at how smartphones moved from consumer life into the workplace, and we may be at the beginning of a redefinition of BYOD here. But it needs to start with an extremely restrictive policy against the use of AI wearables and similar devices.”

He added, “organizations need to hold the line against making personal recordings in the workplace and maintain not only their compliance standards, but their workplace culture. This restriction cannot go as far as an outright ban; look at how Walt Disney World got caught up in a lawsuit after telling an employee she could not use Meta glasses. Still, this exception can be made narrow, and it should be made clear that other employees must be alerted when they are being recorded.”

Google, Microsoft, OpenAI, and others want to help enterprises demonstrate that their AI applications are behaving themselves through the creation of a new foundation.

The Appia Foundation will, it explained rather impenetrably, “establish modular specifications that provide a connecting layer to bridge foundational global standards with practical, trusted assessments across the global AI value chain.”

Those specifications will help AI users ascertain whether the systems they are using meet all the obligations that apply to them in the form of standards and regulations, it said. It’s a challenging task with so much regional variation in requirements, and where the EU, for example, is more tightly controlled than the US.

The Foundation has established a set of criteria to demonstrate conformity with what is expected. There are two layers: the Requirements and Guidance layers will help users determine what is actually required, while the Assessment Enablement layer will look at how those requirements are evaluated.

Appia stressed that what it is offering are not standards — which are set by recognized international bodies such as ISO/IEC — but a means of assessing what those standards mean and how they can be used by organizations. However, the Foundation said that some of the criteria that it is introducing may become standards themselves after a period of time.

The Appia Foundation is hosted by the Linux Foundation’s Joint Development Foundation, and its other members include Arm, Ericsson, Mastercard, Mitsubishi Electric, Omron, Schneider Electric, and Siemens. It is also looking to bring academics and government into the fold, so that it can establish an advisory board.

When it comes to AI deployments, IT leaders are often caught in an awkward middle space, trying to reconcile conflicting directives from senior management with constantly changing AI models, capabilities, and costs; data governance and security needs; and the limitations of their own team.

“Very few real benefits can be attained by simply purchasing an AI product and giving it to employees. Vendors have been overselling that fallacy for the past three years,” said Nader Henein, a Gartner VP analyst.

“The reality is that strong AI value and consistent ROI are almost always a result of deep and intentional integration of AI capabilities into existing workflows. For that you need specialized teams, which do not come cheap, and organizations have been recruiting those teams in a variety of ways,” Heinen said.

Among the options available to IT leaders looking for help with AI deployments are traditional IT consultancies, AI-specific consultancies, and independent contractors. Large enterprises with deep pockets can consider acquiring an AI firm and integrating its technology and expert staff. The use of open source to reduce vendor lock-in is a strategy that can sit on top of those others, an approach that Capital One has used. 

But the option that has been getting the most attention recently is bringing in forward-deployed engineers (FDEs), teams of experts from AI vendors that embed with a customer’s in-house engineers to oversee AI rollouts within the enterprise environment. Both OpenAI and Anthropic have recently announced FDE offerings, for example, and Microsoft is partnering with consulting giant EY in a new FDE program for agentic AI deployments.

Engineering teams employed by AI vendors have key strengths, such as understanding their models better than anyone else, having experience integrating those models into different types of enterprise environments, and knowing about upcoming model capabilities before they’re announced. But they also have the obvious drawback of vendor lock-in. Even if future rollouts are not within their contracted deliverables, those vendor employees could subtly influence a client’s future AI efforts. 

Flavio Villanustre, CISO for LexisNexis Risk Solutions, cautions IT executives to move into FDE programs carefully. 

FDEs “are financially incentivized to grow customers’ use of a vendor’s AI products and to create stickiness with that vendor’s services,” he said. “While FDEs may be a reasonable value-added service by the AI vendor, customers should always find other unbiased expert opinions that can evaluate competitive solutions across multiple vendors.”

This is particularly important at a time when “investor-subsidized AI token business models are starting to show cracks,” Villanustre said. “Also, in the current rapid pace of innovation in this field where AI vendors are constantly leapfrogging each other, retaining the agility to move from one vendor to the next could create significant competitive advantages.”

Analysts, consultants, and other industry experts who spoke with Computerworld about FDEs echoed Villanustre’s caution, citing concerns around hidden costs, confidentiality, observability, and vendor lock-in.

Long-term costs and vendor lock-in

A key issue that IT executives need to consider is how long the FDE teams will be needed. The enterprise will likely need an ongoing series of AI deployments synced with the current AI model(s). If help is needed today, why would that change tomorrow?

Enterprises tend to overlook those longer-term costs, said John Sangyeob Kim, an AI engineer at software development vendor Solidroad.

“Deployment is maybe 20% of the total cost. The other 80% is keeping the system running through model upgrades, data drift, and edge cases that only appear after months in production,” Kim said. “Most contracts price the first part and assume the rest. Deployment isn’t the hard part of enterprise AI anymore. The next eighteen months are.”

And whether it’s intentional or not, FDEs will naturally favor their own product portfolio — it’s what they know best.

“FDEs from model labs are good at making their own models work in your environment. They are less suited for multi-model systems, because their incentive is to keep you inside their ecosystem,” Kim said.

Sanchit Vir Gogia, chief analyst at Greyhound Research, said IT leaders should look at the FDE model as a strategy involving ongoing operational power. 

“Whoever shapes the deployment pattern shapes the enterprise’s future muscle memory. Whoever owns the evaluation layer owns the truth layer. Whoever controls the integration logic controls the dependency map,” Gogia said. “This is why the FDE model matters. It is not just another delivery option. It is the frontier AI vendor moving closer to the customer’s workflow, operating model, and decision architecture.”

That proximity cuts both ways, Gogia noted. “FDEs are embedded inside the customer’s [environment], but they are also connected to the vendor’s commercial center of gravity. Their instinct will be to build around the model family, tooling assumptions, deployment patterns, and product roadmap they know best. This is perfectly natural. It is also precisely why CIOs must be cautious,” he said.

Allowing AI vendor employees an outsized say in enterprise deployment decisions could lock in model vendor dependency, which in turn will fuel high prices that can’t be fought effectively.

“FDEs can accelerate deployment and deepen dependency at the same time,” Gogia said. “Frontier AI vendors are no longer content to sell access to models. They increasingly want to shape how enterprises deploy intelligence. That is a larger prize.”

What happens when the FDE team leaves?

FDE post-departure risks are severe and often underappreciated, according to Justin Greis, CEO of consulting firm Acceligence and former head of the North American cybersecurity practice at McKinsey.

For one thing, the FDE team learns a massive number of operational details from the enterprise deployment. Although NDAs and confidentiality contracts protect any data accessed, they often don’t regulate observed processes and procedures. 

“The learnings are absolutely going to be taken from client to client,” Greis said. “Whoever helps deploy AI will learn far more than what appears in the statement of work. They will learn the real workflows, the undocumented exceptions, the data-quality gaps, the approval bottlenecks, the security workarounds, and the places where the business depends on a few people knowing what to do when the process breaks. That knowledge may be as sensitive and precious as the data itself.”

Another critical but often overlooked issue is how much meaningful control will IT have over the project if and when the FDE team leaves.

“The danger is not using outside help. Most companies will need outside help,” Greis said. “The danger is using outside help in a way that leaves the enterprise less capable and more dependent when the engagement is over.”

It is precisely those operational decisions that IT often neglects, said Solidroad’s Kim.

“The best predictor of success is not the vendor. It is whether one internal engineer truly understands the system before the implementer leaves. What matters is who owns the evaluation loop after the demo,” Kim said.

“What happens to our prompts, scorers, and guardrails when the model version changes? If we paused this engagement tomorrow, what would actually stop working, by design or by accident?” Kim asked. “Where do you want the enterprise’s AI learning, control, and dependency to live after the engagement is over?”

Kim argues that observability — the ability to understand and manage all elements of a complex enterprise environment — is a critical function to which IT often gives insufficient attention. Determining whether the project uses the enterprise’s observability stack or the vendor’s observability stack is crucial.

“If the implementer is using their observability stack, that is fine during the build, but you need a plan to migrate it to something you own before they leave; otherwise the visibility walks out of the door with them,” Kim said. “If they are using yours, that is the best case. It means they are working inside the system your team will operate long-term.”

A major problem crops up when they are using neither the enterprise’s nor the vendor’s observability stack. “Neither means they are building the system without any production observability layer at all, and you inherit a system you cannot see into. The first time something breaks in production, you have no traces, no failure history, and no way to tell whether the issue is a model regression, a data problem, or a code bug,” Kim said.

“If observability was not a priority during the build, evals and regression testing usually weren’t either, so you are inheriting a system you cannot measure and cannot safely change. That’s the worst possible handoff position,” he said.

Weighing the alternatives

While the FDE approach is not new, it is just now beginning a surge in popularity, and there are a finite number of such specialists available. That means not all companies even have the option of using FDEs.

This availability disconnect is especially prominent for non-US deployments, where on-site FDEs are rarer, said Gartner’s Henein. “Where is the development happening? There may not be FDEs available in that region,” he said. 

There are plenty of other places enterprises can turn to for AI help. Ishraq Khan, CEO of coding productivity tool vendor Kodezi, encourages IT executives to consider a wide range of options but notes that all approaches have major drawbacks.

“Traditional consultancies are usually stronger at governance, process, compliance, and organizational coordination. They know how large enterprises operate politically and structurally. The downside is that many move slower and often lack deep frontier AI specialization,” Khan said.

Gogia from Greyhound Research put it more colorfully: Traditional IT consulting firms “know how to get legal, risk, security, finance, HR, and business units into the same room without anybody setting fire to the carpet. For regulated enterprises, that matters,” he said.

Specialized AI consultancies have a different set of strengths, Khan said. “AI-native consultancies move much faster and are often more technically current, but many are still immature operationally. Some can build impressive demos without fully understanding long-term maintainability, governance, or production reliability.”

Greis from Acceligence commented on two other options for bringing in outside AI help. Using an independent contractor “can be great for eval design, architecture reviews, red teaming, agent design, or getting a stalled team unstuck,” he said, but it can increase the risk of “key-person dependency,” where a single external person is the only one who understands the system.

As for purchasing an AI firm and onboarding its employees, a practice known as “acquihiring,” Greis said it can work well when the AI capability and expertise being brought in are truly strategic for the acquiring enterprise. But there is a risk that the acquired team will be smothered by the parent company’s bureaucracy: “You buy a speedboat, bolt it to an aircraft carrier, and then wonder why it stopped moving,” he said.

Finally, an open-source strategy can give companies flexibility and reduce vendor dependence, but “many companies underestimate the operational burden that comes with it,” Kodezi’s Khan said. “Open source only helps if the organization has the internal talent and discipline to maintain it properly.”

Bottom line: enterprises need to define their true objectives before deciding on an approach. Khan offered several key questions for CIOs to consider: “Who owns the deployment after implementation? Can we move providers later without rebuilding everything? What happens if the vendor relationship changes or disappears? Are we optimizing for short-term deployment speed or long-term operational resilience?”

In any scenario where outside firms have direct access to enterprise systems, IT needs to be kept fully in the loop. “The worst outcome is when an enterprise successfully deploys AI but no longer fully understands how its own systems operate underneath,” Khan said.

External help for AI deployments: 6 options

	Pros	Cons
AI vendor FDEs	+  Best expertise on the main model being used	–  Vendor lock-in –  Operational detail leaks
Traditional IT consultancies	+  Best understanding of change management, legacy integration, global rollout, governance, and operating-model redesign	–  Can be too slow, too expensive, or too generic
AI consulting firms	+  More practical AI deployment experience than traditional consultants +  Less vendor lock-in than model-provider FDEs	–  May not sufficiently understand enterprise-grade requirements: security, identity, auditability, compliance, incident response, cost controls, and long-term maintainability
Independent contractors	+  Useful for precision tasks: eval design, architecture reviews, red teaming, agent design, or getting a stalled team unstuck	–  Risk of ‘key-person dependency’
‘Acquihiring’ an AI firm	+  Works when the acquired capability is truly strategic	–  Acquired team can be smothered inside existing bureaucracy
Deploying open-source products	+  Reduces dependency on one model vendor +  Attractive for data sovereignty, control over enterprise systems, cost efficiencies, and regulated environments	–  Enterprise takes on full responsibility for security, patching, evaluation, deployment, monitoring, and lifecycle management

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.

KB5078885 (OS Builds 19045.7058 and 19044.7058)

Release date: March 10, 2026

Applies to: Windows 10 ESU

With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. This targeting is based primarily on client device diagnostic data; due to limited data, servers are unlikely to qualify, though not explicitly excluded. Devices receive new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.

Windows 10 2022 Update (version 22H2)

Release date: October 18, 2022

The Windows 10 2022 Update is, in Microsoft’s words, “a scoped release focused on quality improvements to the overall Windows experience in existing feature areas such as quality, productivity and security.” In other words, there’s not much new here, although Computerworld blogger Susan Bradley did uncover a handful of new group policies in the release.

Home and Pro editions of the 2022 Update will receive 18 months of servicing, and Enterprise and Education editions will have 30 months of servicing.

To install the update, go to Settings > Update & Security > Windows Update and select Check for updates. If the update appears, select Download to install it.

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.

For more details, see Microsoft’s “What’s new for IT pros in Windows 10, version 20H2.”

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.

For more details about new features for IT, see the Microsoft blog posts “Windows 10 Creators Update advances security and best-in-class modern IT tools” and “What’s new in Windows 10, version 1703 IT pro content.”

The age-old IT defense when compliance violations are investigated by regulators is to try and keep a low profile — and hope no one looks too closely. But with enhanced SEC interest in all data breaches encouraging regulators around the globe to take those closer looks at IT, data breach disclosure rules are becoming more strict.

While that might be unsettling for cybersecurity executives, it is also disturbing news for IT admins, who could find themselves under a remarkably uncomfortable spotlight. 

Consider this recent move by the New York State Department of Financial Services against the Delta Dental Insurance Company. State officials hit the insurance company for improper and inconsistent enforcement of its own data retention policies; improper incident response plan protocols; and improper notification of the security incident itself. 

The company was fined more than $2 million.

The data retention violations are perhaps the most problematic. Had that policy been enforced properly, much of the stolen data would have been destroyed long before the attackers could have accessed it. 

It’s not simply a matter of whether the IT rules for retention were sufficiently strict. Some regulators — and especially the US Federal Trade Commission (FTC) — focus extensively on companies who don’t do what they say publicly. If a corporate website promises something to customers, the FTC will hold companies to their word. 

Think about that the next time you assign a summer intern to handle your website’s copy. 

Inconsistent implementation of data retention policies can deliver other legal headaches. Having a good policy approved by the general counsel is fine, but it means nothing if all of your people do not follow it strictly. 

Let’s say one of your business units is being sued for having done something naughty. Opposing counsel subpoenas your business records, including emails from a few years ago. Your attorney responds that those email records no longer exist; they were deleted last year in accordance with corporate policy on data retention that says everything of a certain nature has to be deleted after one year. 

Fair enough. But what if opposing counsel in a deposition asks,“Really? Does that policy apply to all records of that nature?” You say that it does. 

“It might interest you to know that we have sworn testimony from four other employees who showed us emails of the same nature that were more than five years old. So why did you adhere to your policy regarding emails that might prove the fraud but somehow you did not delete others? Sounds a little selective, no? I think the judge would agree.”

In the dental case, the company had a strict policy on retention rules. But corporate software was programmed with “the ability to shorten, extend, or disable MOVEit Transfer’s default retention settings on a folder-by-folder or file-by-file basis.” 

The regulators then swooped in because the insurance company “had no written policy or procedure for requesting, reviewing, or approving such changes to folder retention settings.”

The best retention policy would, in theory, have no exemptions. But if you’re going to allow exemptions, you need a precise policy documenting how and when they can occur. There should be a required form so that a manager can write out the reasons for this specific exemption.

The New York state document is an important one to carefully review; it provides an excellent roadmap to how compliance can go wrong — and useful information on how to keep something similar from  happening to your company.

A variety of new features are being gradually rolled out in this build, including several for Copilot+ PCs. The Click to Do context menu in Copilot+ PCs now has a streamlined design that makes it easier to access frequently used actions such as Copy, Save, Share, and Open. In Copilot+ PCs you can now also use Windows Studio Effects, which provide AI-powered camera enhancements, on an additional camera such as a USB webcam or your laptop’s built-in rear camera.

New features being rolled out gradually to all Windows 11 PCs include a simplified File Explorer context menu for easier navigation. Common actions like Share, Copy, and Move now appear in a single organized menu.

A variety of bugs have been fixed for all PCs, including one in which the Local Security Authority Subsystem Service (LSASS) could become unstable due to an access violation.

There are two known issues in this build, one in which when opening File Explorer in dark mode, the window might briefly display a blank white screen before loading files and folders. In addition, the password icon is missing or invisible in the lockscreen sign-in options on some PCs. (Here’s a workaround for the latter bug.)

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

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.

(Get more info about KB5060829 Preview.)

KB5063060 (OS Build 26100.4351) Out-of-band

Release date: June 11, 2025

This out-of-band update replaces the KB5060842 Patch Tuesday release, fixing a bug in which Windows sometimes restarted unexpectedly when users opened games that use the Easy Anti-Cheat service.
