Microsoft: Certain Windows PCs are unable to shut down following the January update.
"Following the installation of the January 13, 2026, Windows security update (KB5073455) for Windows 11, version 23H2, some PCs with Secure Launch are experiencing issues where they cannot shut down or enter hibernation. Instead, these devices restart," Microsoft explained in a Windows release health dashboard update on Thursday.
"Secure Launch employs virtualization-based security to safeguard the system against firmware-level threats during startup. KB5073455 is exclusively available for Enterprise and IoT editions of Windows 11, versions 23H2."
Until a permanent solution is provided for this issue, Microsoft has offered a temporary workaround that requires affected users to shut down their device via the command prompt using the following command:
shutdown /s /t 0Currently, there is no workaround for systems set to enter hibernation.
"Until this problem is fixed, please ensure you save all your work and shut down when you finish using your device to prevent it from running out of power instead of hibernating," Microsoft added.

Microsoft is also working to resolve a bug caused by the January 2026 KB5074109 Windows security update, which leads to connection failures and authentication errors during Remote Desktop connections to Cloud PC sessions.
On Tuesday, Microsoft addressed another known issue that was causing security applications to flag a core Windows component on client (Windows 10 and Windows 11) and server (Windows Server 2012 through Windows Server 2025) platforms.
