Microsoft just announced a Windows and Surface event for October 7, 2026. The event will be held in San Francisco and will focus on "how local AI will shape the next chapter of the PC." It will start at 10 AM PT / 1 PM ET.

Microsoft CEO Satya Nadella will be at the event, as will Surface chief Pavan Davuluri. NVIDIA CEO Jensen Huang will also be there, so we can expect to see RTX Spark discussed on stage.

RTX Spark is NVIDIA's new superchip. It powers the Surface Laptop Ultra and Surface RTX Spark Dev Box. Microsoft already announced those devices but has not shared key details yet, including pricing and availability. The event in October could be a chance to share more about the devices and the RTX Spark in general.

Microsoft is also expected to highlight improvements to Windows 11. The tech giant is deep into its Windows K2 initiative that aims to reduce pain points in the operating system and smooth the overall experience. We've seen some early wins from that initiative, such as the option to resize and move the Taskbar on Windows 11.

But Microsoft still has a long way to go before Windows 11 is redeemed in the eyes of many. Windows updates often ship with bugs and the operating system still has mismatching UI elements. Fixing Windows 11 is a large project that will take time, and Microsoft would be wise to show what it's already done to improve the OS and point to what's on the way.

While Microsoft could always surprise us with more hardware announcements, its quote about "how local AI will shape the next chapter of the PC" aligns well with devices we already know are on the way. The Surface Laptop Ultra and Surface RTX Spark Dev Box are designed to run AI locally.

Based solely on that quote, we could see Microsoft discuss Project Zenith at the event. That's the codename of a new class of devices aimed at developers that want to build apps and local AI experiences.

Microsoft is having a bit of a rough September when it comes to bugs. Another issue has been discovered in Windows 11. This time, it's Excel's copy and paste feature that's been broken by an OS update.

That bug was discovered shortly after Microsoft confirmed issues with Hyper-V Linux folder shares, Remote Desktop, and USB audio. Those have since been fixed through an out-of-band update, but the Excel bug has not been fixed yet.

Here's what's wrong, according to Microsoft:

"In Microsoft Excel 2024, 2021, 2019, and 2016, the paste operation might fail silently. Although users try to paste content, the source remains selected and the destination is unmodified. When this issue occurs, users receive no indication of the failure, such as a beep or error message. Microsoft is researching the issue and will post more information in this article when the information becomes available."

The September Patch Tuesday update has almost 1,000 security fixes, so it is important to install it on PCs. But it may be worth holding off a bit if your workflow would be hindered by lingering bugs.

I don't want to come across as a doomsayer. The sky is not falling because copy and paste in Excel is broken. But it's frustrating to see bugs creep into Windows 11 updates.

Microsoft is aware of negative feelings many users have toward Windows 11. The company has a Windows K2 initiative that aims to reduce pain points and improve the overall Windows 11 experience. Part of that initiative centers around improving Windows updates.

On paper, Microsoft is trying to reduce how many updates people need to install each month. But I've had to install several Windows 11 updates just in September, including the out-of-band update that fixed the audio issue.

Windows 11 just received an out-of-band update that addresses several issues with the operating system. The September Patch Tuesday update includes almost 1,000 security fixes and other improvements, but it also had bugs that broke folder shares in Hyper-V-based Linux virtual machines, Remote Desktop Services, and certain audio devices.

Microsoft released the out-of-band update shortly after the issues were confirmed. It should download automatically in the background if you're running Windows 11 versions 26H1, 25H2, or 24H2. You can also grab the update through the Microsoft Update Catalog.

For the sake of clarity, Microsoft refers to these types of updates as out-of-band updates, but many people refer to them as emergency updates because installing them is urgent enough to ship the fixes immediately.

Here's a quick summary of the fixes, as outlined by Microsoft:

"Microsoft has identified issues that affect some devices after installing the September 2026 Windows security update, released September 8, 2026. On affected devices, host folder shares might be unavailable in Hyper-V-based Linux virtual machines, Remote Desktop Services might stop responding, which can prevent new sessions from being created and can prevent local and remote sign-in, and some USB Audio Class 1.0 devices might fail in multichannel audio modes."

Out-of-band updates have been released more in 2026 than in previous years. Some bugs in Windows 11 have required multiple patches.

When we publish a piece on Windows Central about a Windows 11 update, it's normal to see comments asking what the update will break. When there are inevitably issues with Windows 11, people ask "what do you expect" or something along those lines.

Obviously, if Microsoft finds issues, it needs to patch them. Emergency updates should be used when needed. My question is: why are they needed more frequently this year?

The situation is so bad that people celebrated the option to pause Windows 11 updates forever.

Microsoft is in the middle of an initiative to improve Windows 11 and reduce pain points in the operating system. But no one will care if they can move the Taskbar to the top of the screen or customize the Start menu if their speakers don't work.

Microsoft has issued an out-of-band update for its recent Windows 11 patch, which has caused a number of bugs and issues. The September 2026 update was just released last Tuesday, and although it packs a number of new features and fixes nearly 1000 security flaws (commonplace in this day and age), there are also a few unfortunate regressions.

The 25H2 update finally reintroduces a movable taskbar, just like we've had since Windows 95, with an option to make the height smaller for compact displays. Likewise, the Start menu now has multiple configurable layouts, and you can toggle each main section on or off. Microsoft also revamped Windows Search — perhaps to finally be useful — and users can now choose to only have it display local results. Explorer got a handy tweak in the form of using KB, MB, GB size indicators, as well.

The update has also surfaced some serious bugs. First off, PCs with AMD Radeon GPUs are crashing, apparently due to the update provoking driver instability. Reinstalling the driver doesn't appear to help, and the reports unfortunately cover most contemporary AMD graphics cards. Microsoft did not mention AMD GPUs specifically in its latest update.

Microsoft noted that it has fixed an issue with Remote Desktop Services where RDS might become unstable, causing connection and sign-in failures.

Microsoft is also aware of an issue with audio output and microphone input going dead. Additionally, there are seemingly reports of audio devices starting up with a botched configuration, like tweaked 3D audio settings or speaker setups. The apparent workaround seems to be putting audio in a standard 2.0 configuration, but Microsoft has now addressed this issue in the emergency patch.

Explorer may display a black screen after logging in, leaving you with a perfectly functioning operating system but no visible UI. The File History backup feature is reportedly not detecting external drives, effectively making it useless. Of particular concern to enterprises, systems administrators, and homelabs, the Remote Desktop Service is also experiencing issues. Last but not least, Microsoft says it has addressed an issue where Claude Cowork is nonfunctional due to the update breaking HC-managed Linux VMs with Plan9 shared folders

Owners of HP and Lenovo systems are also advised to consider holding off on this update. Ever since the August 2026 patch (and now, cumulatively, with the September update), there are reportedly serious issues on both camps. On the HP side, there are instances of the update triggering BIOS corruption, leading to a failed install with no ability to recover the OS — though seemingly the OEM has published a new BIOS revision, so it's hard to say which side is to blame. Meanwhile, Lenovo users might have their machines black-screen or shut down out of the blue, seemingly due to power mismanagement.

While it's heartening to see that Microsoft has significantly increased its Windows development speed and is seemingly listening to customer feedback, a string of bugs after a major feature update are still common.

The latest Windows 11 update gives you plenty of reasons to upgrade, including hundreds of security fixes. But it also includes some bugs that range from frustrating to workflow-breaking.

Microsoft recently confirmed that a bug in Windows security update KB5124008 can cause some audio devices to fail. Affected systems will see one or more of the following issues:

• The device displays an error in Device Manager: "This device cannot start (Code 10).” 
• No audio output.
• Volume controls are unresponsive or remain at zero. 
• Sound settings are unresponsive or unavailable. 
• Some devices might function in standard stereo configurations but fail when using multichannel audio features, including 8-channel or 3D audio modes. Some customers have reported that they're able to restore audio in these cases by switching to 2-channel mode. 

I believe my PC was affected by this bug. After installing the most recent Patch Tuesday updates, my external USB speakers stopped working, and Windows automatically defaulted my audio output back to my docked laptop's built-in speakers.

The problems only affect USB Audio Class 1.0 devices. Just about any operating system or platform that supports USB audio works with USB Audio Class 1.0. That class was the first standard for audio devices and shipped in 1998. There are USB microphones, headsets, speakers, and many other devices that fall into the category.

Because some modern platforms (most notably gaming consoles like the PS5 and Nintendo Switch) do not support newer standards, headsets and other peripherals are often made to be USB Audio Class 1.0 devices so they work everywhere.

The bug affects Windows 11 versions 26H1, 25H2, and 24H2. Microsoft has confirmed the issue but has not released a fix at this time.

You may be able to workaround the bug by switching to 2-channel mode, but that is not a permanent fix. You can also uninstall the KB5124008 update, though it may be better to just wait for an official fix or to find a workaround.
