@JChill:
It's fixed. The original issue was caused by an incomplete installation of the LCU/SSU update. It's now rectified.
You can revert to the previous state (from clean boot to normal startup) if you wish.

Tough one for me, thanks for any and all help!
New PC and Windows 11 install
Windows 11 Home
Version 24H2
OS build 26100.2894 Windows Feature Experience Pack 1000.26100.36.0
Busy at work and took me weeks to migrate files and reinstall programs on new PC.
No problems with new system, everything running and no crashes.
Saw some windows update fails in March but antivirus and drivers were all updating so ignored.
Noticed repeated update fails this month

Stupidly dug in this time and much increased confusion and concern from common recommendations.
Removed all hardware, no programs running same results.
Manual attempt at update from Windows catalog standalone runs but returns
"This update is not applicable to your computer. check the documentation to find out if you need to install another update first"
Possible I'm missing an update that is hanging the new ones, but can't figure out how to sort that.
Windows Update troubleshooter returns
"The Windows Update diagnostic failed to run" **** and recommends talk to an agent
Dism /Online /Cleanup-Image /CheckHealth run in admin cmd returns
Version: 10.0.26100.1150

The component store cannot be repaired.
Dism /Online /Cleanup-Image /ScanHealth run in admin cmd returns

Class not registeredSFC /ScanNow run in admin cmd returns
Windows Resource Protection could not start the repair service.
Fix problems using Windows Update "This option is currently unavailable"
Go back "This option is no longer available on this PC"
Any other way to repair Win 11 to avoid redoing all programs, drivers, and files?
I'm stumped.

Please run the fixlist below.
Post fixlog.txt.
That should resolve the issue in most cases.
Restart Windows and launch "optionalfeatures.exe" to test.

The first method is to reset the Windows update components using the PowerShell command below.
This method will reset the Software distribution folder where the temporary file of the update is saved, and re-register the internet connection as well.
Open Powershell with Admin or CMD with Admin (Press Windows key + X then click Windows Powershell(Admin))
Copy each line of command to Powershell then press enter (one line at a time)
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc
Restart the device and check it again, just ignore any errors in the command line if you encounter them.
If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
Kindly follow the steps from this link:

2025-04-17T16:01:23+00:00 Ok, I will try the reset the Windows update commands.
After I run them and restart, I should attempt windows update again and if that does not work back up all files and attempt in place upgrade?
Thanks

2025-04-17T16:23:16+00:00 I think there is some CBS corruption. A repair installation is not possible unless the issue is fixed.
Please download my ssudiag.vbs (right-click and save link as in your browser).
Run the script and post the output here.
