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.
