Windows 11 Update KB5132061 Fails to Install on Some PCs: What Microsoft Says
PCs that installed October's optional preview update are hitting errors with the November security release. Microsoft says a fix is rolling out automatically.
If your PC refused to install this month's Windows 11 security update, you are not alone. Microsoft has acknowledged that KB5132061, the November 2026 cumulative update, fails to install on some devices.
Who is affected
The problem hits PCs that had already installed October's optional preview update. On those machines, the November update can roll back partway through and show one of several error codes:
- 0x80070306
- 0x800f0989
- 0x800f0993
Optional preview updates are released late each month to let people test upcoming fixes early. They are not installed unless you choose them, which is why most home users will not see this issue.
The fix
According to BleepingComputer, Microsoft said it is pushing a server-side fix and that affected devices should be repaired automatically within 24 to 48 hours of 10 a.m. Pacific time on November 11. No manual download is needed. Restarting your PC and checking Windows Update again after that window should allow the update to install.
Because this update also patches security holes, it is worth confirming it finally installed. Go to Settings, then Windows Update, then Update history, and look for KB5132061 in the list.
