Windows Update KB5010342 fails to install Windows 10 version 21H1

I would've lost a bet that a restart wouldn't install the security update (s)

As Inspector Jacques Clouseau used to say, the case is solve -ed

Sorry for the late reply @steve108
After I completed the Repair with In-Place Upgrade successfully, Windows tried installing CU (KB5010342)
It failed, unfortunately, along with another CU for .NET Framework

I'm guessing another attempt by restarting the PC will likely fail the second time too

 

Windows Update KB5010342 fails to install Windows 10 version 21H1

February Patch Tuesday Update failed With Error 0x80070003

do not have group policies in force
do not use 3rd party utilities to block telemetry
have not disabled WU recently
do not use a VPN
do not have any 3rd party security sftw installed

Steps I have already taken:

#1) Ran SFC /verify - Windows Resource Protection found integrity violations
CBS log shows > Warning: Overlap in Directories (Windows\Program Files) , (Windows\SysWOW64), and Windows\Program Files (x86). Warnings state these Directories are owned twice or have its security set twice

#2) Performed a clean boot and then Reset Windows Update in How to Reset Windows Update in Windows 10

#3) Ran Windows Update troubleshooter - The result fixed 2 issues (atttached screenshot)

#4) Restarted system to install Update again after WU downloaded KB5010342 - message received from second attempted update : We couldn't complete Update. Undoing Changes"

returning system to restart normally needed to wait to be done on the 2nd reboot. (1st reboot) performed during the WU reset process. (2nd reboot) performed to return system to restart normally Perform a Clean Boot in Windows 10 to troubleshoot software conflicts
