Microsoft confirmed a Windows shutdown/hibernation bug introduced by the January 13, 2026 security updates (e.g., KB5073724) that causes Secure Launch-capable, VSM-enabled Intel-based systems running Windows 11 23H2, Windows 10 22H2, and Windows 10 Enterprise LTSC (2019/2021) to restart instead of powering off; AMD and ARM64 consumer PCs are unaffected. An out-of-band update (e.g., KB5077797) partially fixes the issue, but VSM-enabled machines remain impacted; Microsoft is preparing a full resolution, and affected users can temporarily force shutdown via Command Prompt using `shutdown /s /t 0`.
