Some Windows 11 users are getting error codes instead of November’s update. Neowin and The Register report that KB5132061 is failing to download or install on some PCs, with errors 0x800f0993 and 0x800f0989 among those reported. Plenty of digits, not much explanation. Source Source
In its report published on November 11, 2026, at 14:55 UTC, The Register said Microsoft listed no known issues for the update and had not provided a statement or explanation. The outlet said it had asked Microsoft for comment. Source
The Sandbox workaround comes with an asterisk
Both outlets trace the workaround to ElevenForum user Forceflow, who reportedly installed KB5132061 after disabling Windows Sandbox and rebooting. Disabling a Windows feature to install a Windows update is quite the detour. Source Source
Windows Sandbox is an isolated, disposable desktop environment used to test software, with changes discarded when it closes, Neowin explains. Its report says the user’s update failure occurred on the desktop where Sandbox was enabled, while their other Windows 11 systems did not experience the problem. Source
The Register also reports installation problems regardless of Windows Sandbox status. Disabling the feature isn’t a confirmed fix for everyone. Source
Neowin suggested DISM repair, SFC scans and the Windows Update troubleshooter as possible troubleshooting options; The Register also mentioned manually downloading the update. Neither report establishes these options as reliable fixes. Source Source
