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.
