Hello,
The error code indicates corruption of Windows Update components. Please try this fix
Open administrative Command Prompt and type following commands one-by-one followed by Enter key.
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Close Command Prompt and see if it resolves the issue.
If issue still persists, try this:
- Search for 'windows powershell' using Windows Search.
- From results, choose Windows PowerShell and select Run as administrator.
- Then type/paste following and press Enter key:
Repair-WindowsImage -Online -RestoreHealth
- Let the command complete, restart your system then.
Let us know if this helps!
I have the same issue;
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Doesn't help, because you can not rename Catroot2, it is locked by other processes, I even tried Safe Mode. Yes, I stopped all services here. Catroot2 still can't be renamed!
I understand your frustration, the issue may be your system is not 100% compatable. I have the same issues with my Dell AIO desktop. The system originally was released with Win 7, and have added more disk space and memory, that helped with getting it to Windows 11, but the newer Windows 11 updates not installing due to hardware requirements. Review system requirements and verify your system is compatable.
