Microsoft has resolved a persistent issue in Windows 11 known as the 'Update and Shutdown' bug, which caused unintended reboots when users attempted to shut down their PCs. This fix comes with the release of the Dev Channel Build 26220.6760.
Bug Fix Details
The 'Update and Shutdown' bug has been plaguing Windows 11 users since its launch in 2021. Microsoft identified that the glitch was due to how cumulative updates managed conflicts like temporary file locks or driver issues. Instead of shutting down, systems would reboot, causing disruption and potential data exposure.
- Microsoft released Build 26220.6760 for the Dev Channel on 2025-09-29.
- This update addresses the bug by refining how updates handle system conflicts.
- Early testing shows the shutdown now behaves correctly in Insider builds.
Availability and Access
The fix is currently available to members of the Windows Insider Program via the Dev and Beta channels. Insiders can enable this update by toggling the option in Settings > Windows Update. Microsoft advises regular users to await the stable release.
This improvement is part of a broader effort to enhance Windows Update reliability and system performance, particularly benefiting older hardware that was more prone to these issues.
