Microsoft’s November 2026 Windows 11 security updates can fail on devices that installed an October preview, with automatic repair underway.

Microsoft released mandatory November 2026 Patch Tuesday cumulative updates for Windows 11 versions 26H2, 25H2, 24H2, and 23H2, including KB5132061 and KB5131087. The packages fix hundreds of previously found vulnerabilities and add File Explorer, AutoPlay, Magnifier, and taskbar changes. Microsoft later confirmed that KB5132061 and other November security updates can stall on a limited set of devices that installed the October non-security preview KB5127936, returning errors 0x80070306, 0x800f0989, or 0x800f0993. Devices that never installed that preview are unaffected. Microsoft said affected devices should self-repair within 24 to 48 hours from November 11, 2026, 10 a.m. PT, then download the update; persistent failures should go to Microsoft Support.
