@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

Image Version: 10.0.26100.2894
Error: 0x80040154
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.

2025-04-18T07:38:03+00:00 Error 0x80070570 means "The file or directory is corrupted and unreadable."
It appears that there is some file or file system corruption.
You may run "chkdsk c: /f" before running the ISO.
If possible, share the latest CBS logs.
