Microsoft issued out-of-band patches to fix bugs introduced by the January 2026 Windows update, including Remote Desktop sign-in failures and a Secure Launch restart issue affecting Windows 11, Windows 10, and Windows Server; affected systems should install the updates via Windows Update or have IT push them in managed environments.
Microsoft’s January 13, 2026 security update KB5073455 for Windows 11 23H2 (OS Build 22621.6491) triggers a shutdown bug on Enterprise and IoT editions, causing devices to reboot instead of powering down or entering hibernation due to interference with Secure Launch (a virtualization-based security feature). IT teams report power-management issues and potential data loss; a workaround is to force shutdown via shutdown /s /t 0, while a fix is promised in a future update. Disabling Secure Launch via Group Policy can restore normal shutdown but weakens boot integrity.
