Has Microsoft fixed the KB5132061 Windows 11 install failures?

Not yet confirmed. Microsoft's KB5132061 page said it would fix affected PCs on its own, 24 to 48 hours after 10am Pacific on November 11, and that window ended at 10am Pacific on November 13. The page shows no resolution note. A device that still fails with 0x800f0993, 0x80070306 or 0x800f0989 now needs a Microsoft Support case.

Which PCs fail to install KB5132061, and with which errors?

Some Windows 11 devices cannot finish the November 10 security update, according to a known-issue entry Microsoft added to its KB5132061 page on November 11. They retry in a loop or stop with 0x80070306, 0x800f0989 or 0x800f0993. The update takes Windows 11 26H2 to build 26300.9974, 25H2 to 26200.9974 and 24H2 to 26100.9974.

Microsoft's entry names KB5127936, the October preview update, as the update being installed, but it does not explain the link. BleepingComputer describes KB5127936 as an optional preview without security fixes. WindowsForum, summarising a BleepingComputer report on Microsoft's statement, says the problem is limited to devices that installed that October preview and that devices without it are not affected. Windows Latest also logged one report of 0x800f0922, which Microsoft's entry does not list.

When did Microsoft's 24 to 48 hour repair window for KB5132061 end?

It ended at 10am Pacific on Friday, November 13, which is 18:00 UTC because US clocks went back on November 1. The 24-hour mark was 10am Pacific on Thursday, November 12. Both counted from 10am Pacific on Wednesday, November 11.

Microsoft says affected devices repair themselves, with no manual action, as long as they are online and get updates through Windows Update. Its page does not say what happens to devices that take updates from WSUS or have no internet access. After 48 hours, the page points anyone whose install still fails to Microsoft Support or the Windows help pages, and WindowsForum's summary says Microsoft told administrators to contact Support.

Does turning off Windows Sandbox fix the KB5132061 errors?

It helped at least one user, and it is not an official fix. Windows Latest reports one user who failed with Windows Sandbox enabled and installed after turning it off, and another who hit the error with Sandbox off, so Sandbox is not the only cause. Microsoft's entry does not mention it.

The steps are to open "Turn Windows features on or off" from Start search, clear Windows Sandbox, select OK, restart, then retry in Settings and Windows Update. Switching the feature off removes Sandbox for anyone who uses it, so test on one failing device first.

What can you try if KB5132061 still fails after the repair window?

Retry Windows Update on a connected device first, since Microsoft's repair is meant to let the update install without user action. If it still fails, Microsoft's page points to its linked manual install instructions and to Support.

Windows Latest adds two options. The Microsoft Update Catalog is one, though one user failed seven times with it, offline installer included, before the update installed. Settings, System, Recovery, Fix problems using Windows Update is the other; it reinstalls the current Windows version and keeps apps, files and settings. A pending Secure Boot certificate update can need two or more reboots, which is an extra restart and not a failure. WindowsForum lists DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow as a community step, and says it is not a Microsoft instruction.

This story reflects Microsoft's KB5132061 page as read on November 14, 2026. It will be updated if Microsoft posts a resolution.
