Windows 11 received a security update earlier this month. As is often the case, Microsoft has discovered some issues with its monthly security update. While known issues are common, they can cause frustration for users affected by bugs and other problems. The most recent Windows 11 security update has four known issues that have been confirmed by Microsoft. The most notable issue is that some people may run into problems with audio devices.
The issue affecting audio devices is more likely to appear if you have a piece of hardware using a USB 1.0 audio driver. Affected systems will not be able to use those types of devices for audio playback. Microsoft is working on a fix for the bug. In the meantime, users can avoid the issue by not using an external DAC during the connection process. Plugging an audio device into a PC directly should get around the issue.
Windows 11 Build 26100.2894, which shipped on January 14 2025, also has an issue that prevents Arm devices from being able to download or play Roblox through the Microsoft Store. Those with Arm PCs can download Roblox through www.Roblox.com.
Microsoft shared a table breaking down all the known issues with the latest Windows 11 security update:
Windows 11 Build 26100.2894 includes several security improvements that help protect your PC. Specifically, the update adds entries to the list of drivers that are considered at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks. It's generally good policy to keep your PC up to date with the latest security update, but if your workflow is broken by the known issues in the build, you can roll back to a previous version of Windows 11.
Microsoft also outlines workarounds and ways to mitigate the known issues, so if you are only affected by one problem, it may be worth trying a workaround before uninstalling the most recent Windows 11 security update.
