REDMOND, Washington, January 14, 2026 – Microsoft released an out-of-band update on Tuesday to fix a widespread issue that prevented some Windows 11 devices from shutting down or restarting properly after the January 2025 security patch (KB5050009).
The problem affected a subset of systems running Windows 11 version 24H2, causing the shutdown process to hang indefinitely or fail silently. Users reported being forced to hold the power button for hard resets, risking data corruption or hardware strain. The bug surfaced shortly after the cumulative update was deployed on Patch Tuesday, January 14.
Microsoft confirmed the issue in a support post, stating: “We are aware of reports that some devices running Windows 11, version 24H2, may experience issues shutting down or restarting after installing the January 14, 202,5 security update.” The company attributed the problem to a compatibility issue with certain third-party drivers and system configurations.
The emergency fix, labeled KB5050092, is now available through Windows Update and the Microsoft Update Catalog. Microsoft advised affected users to install it immediately, noting that it resolves the shutdown hang without requiring a clean boot or additional troubleshooting steps in most cases.
The bug did not cause widespread outages or data loss, but it frustrated users who rely on reliable power management. Forums and social media saw reports of the issue within hours of the original patch release, with some enterprise IT teams delaying deployment to avoid disruptions.
Microsoft has not disclosed the exact number of impacted devices, but the rapid out-of-band release indicates significant user impact. The company typically reserves such fixes for critical or high-severity issues.
The incident follows a pattern of post-Patch Tuesday problems in Windows 11 24H2, including earlier audio and Bluetooth glitches that required separate hotfixes. Microsoft has committed to improving update quality, with enhanced testing and staged rollouts for future releases.
Users who already installed the January security update should check for KB5050092 in Windows Update settings. If the shutdown problem persists after applying the fix, Microsoft recommends running the built-in troubleshooter or contacting support.
