Thanks for the screenshot.
The reported build is not from update KB5065426, which means that Windows is mistakenly saying that the update was installed successfully.
I suggest doing the following:
Run the Windows Update troubleshooter and try to install the update.
https://support.microsoft.com/en-us/windows/windows-update-troubleshooter-19bc41ca-ad72-ae67-af3c-89ce169755dd#WindowsVersion=Windows_11
If it persists, rename the software distribution folders as instructed below:
- Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
- Run the following commands at the Command Prompt one at a time:
net stop bits
net stop wuauserv
net stop cryptsvc
ren %systemroot%\softwaredistribution softwaredistribution.bak
ren %systemroot%\system32\catroot2 catroot2.bak
net start bits
net start wuauserv
net start cryptsvc
- After all these commands are completed, close the Command Prompt window, restart your computer, and then try to update Windows.
If it persists, use the system file checker to repair possible corrupted or missing system files.
- Open Start and type cmd, right-click on "Command Prompt", and select "Run as administrator".
- Run the following commands at the Command Prompt one at a time:
dism.exe /online /cleanup-image /scanhealth
dism.exe /online /cleanup-image /restorehealth
dism.exe /online /cleanup-image /startcomponentcleanup
sfc /scannow
Note: Pay close attention to the results of the commands. This will help you determine whether the procedure was completed successfully or if there was a problem. If you get any errors, let me know the error message that was displayed.
- Then restart your PC and see if you can update.
If it persists, download and install the update that is having problems manually.
