Windows 11 Patch KB5077181 Triggers Infinite Restart on Some Devices

Microsoft's February 10, 2026 security update KB5077181 for Windows 11 versions 24H2 and 25H2 appears to trigger boot loops on affected devices, forcing multiple restarts; while it patches 58 vulnerabilities (including six zero-days) and ships new Secure Boot certificates to improve boot integrity, users report login failures with System Event Notification Service errors, DHCP connectivity losses, and install errors such as 0x800f0983/0x800f0991, prompting uninstall guidance via Control Panel or Windows Recovery Environment and a suggested SFC scan; enterprises should test via WSUS and monitor health while Microsoft has not publicly acknowledged the issues.

Microsoft patches Windows 11 shutdown and remote-login bugs with emergency out-of-band fix

Microsoft issued an out-of-band emergency patch for the January 2026 Windows security update that fixes a shutdown/hibernate bug on some Windows 11 PCs and restores remote login via credential prompts on Windows 10/11 devices; the fix also addresses Secure Launch startup-security issues. Some users still report lingering problems like blank screens or Outlook Classic crashes, and Microsoft noted related fixes from October 2025 for Windows Recovery Environment. Windows 10 users can continue with Extended Security Updates if they’re not ready to upgrade.

Windows 11 Shutdown Bug Emerges After January Patch

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.

Microsoft and Google Warn of Active WSUS and Windows Service Exploits

A security update for Windows Server Update Service (WSUS) addressing a critical vulnerability has inadvertently disabled hotpatching on some Windows Server 2025 devices. Microsoft has halted the update for hotpatch-enrolled systems and released a new patch (KB5070893) that fixes the vulnerability without disrupting hotpatching. Administrators are advised to pause updates, install the new patch, and monitor their systems for continued security and stability.
