October and November 2025 LCUs Roll back with Error 0x800F0922

If the October and November 2025 updates roll back with the error 0x800F0922, this post has the solution. The same issue occurs when installing the Windows 11 updates KB5066835, KB5070773, KB5067036, KB5067036, KB5068861, Windows 10 update KB5066836, and KB5066836 (OS Build 14393.8519) update for Server 2016. The following fix can be applied in that case.

Resolution

This issue occurs if the subkey {53e3d721-2aa0-4743-b2db-299d872b8e3d} already exists under the Publishers key.

To resolve the issue, open the Registry Editor (regedit.exe) and delete the following key after exporting it:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Publishers\{53e3d721-2aa0-4743-b2db-299d872b8e3d}

If necessary, delete the following key as well.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels\Microsoft-Windows-Store/Operational
