shutdown regression

About this tag
The shutdown regression tag covers a specific Windows 11 bug introduced by the January 2026 Patch Tuesday update (KB5073455). Affected systems with System Guard Secure Launch enabled restart instead of shutting down or hibernating. Microsoft acknowledged the issue and released emergency out-of-band updates on January 17, 2026, along with a manual command-line workaround. The regression primarily impacts Windows 11 version 23H2 Enterprise and IoT editions. Discussions include triage of the patch, the Secure Launch feature interaction, and Microsoft's response with OOB fixes for both the shutdown problem and related Remote Desktop authentication failures.
