Microsoft admits Windows 11’s emergency update still breaks audio, and a fix may not arrive until October

Windows 11 is facing ongoing challenges with audio functionality following recent updates, particularly with the emergency update KB5129195 released on September 14. This update aimed to fix issues from the September Patch Tuesday update (KB5124008) but has led to new problems, including compromised audio output on some devices and disruptions in secure trust relationships for enterprise systems. Users have reported error messages like “This device cannot start (Code 10)” in Device Manager, and issues with USB audio devices. Microsoft is investigating these audio problems but has not provided a timeline for resolution. Additionally, there are reports of GPU issues on AMD systems, including driver timeouts and black screens, affecting various Radeon models such as RX 6600, RX 7700 XT, RX 7800 XT, RX 7900 GRE, RX 7900 XTX, and RX 9070 XT. Some users found that uninstalling the September update alleviated these problems, but the emergency update KB5129195 does not address the GPU errors.

On September 14, 2026, Microsoft released KB5129195, an out-of-band cumulative update for Windows 11 versions 24H2 and 25H2, transitioning systems to build 26100.9457 for 24H2 and 26200.9457 for 25H2.

Microsoft confirms Windows 11’s update kills audio on some PCs, and the bugs keep piling up

Windows 11 update KB5124008, released on September 8, has caused significant audio issues for users, including failure of audio devices to initialize or produce sound, and problems with microphones and multichannel audio.

Windows 11’s useless Copilot key finally does something, you can map it to right-click

Recent updates from Microsoft allow users to remap the Copilot key on Windows 11 to either the Right Ctrl key or the Context Menu key.
