I am unable to update windows

Question

I am unable to update windows

KGS 40

When I click on update and shut down, it goes through downloading the updates. Then, it goes to diagnose and then repair. Thereafter, it downloads updates. Next it says 'Something went wrong. Undoing Changes.' Then, the computer restarts without installing the updates.

Thank you for updating me with that information.

Let's start with a few things you can try:

Please try to run SFC and DISM to check for any system errors and corrupted files. https://support.microsoft.com/windows/using-system-file-checker-in-windows-365e0031-36b1-6031-f804-8fd86e0ef4ca Restart your computer

Reset Windows Update components manually Press Windows key+X then select either Windows PowerShell (Admin) or Terminal (Admin) Copy each command line into PowerShell or Terminal, and 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 your computer

Thank you again for your help and suggestions.

I ran DISM. It took a long time but returned without any problem finding. SFC, however, detected a corrupt file; so, I ran it again. The second time, no problem was identified.

I then found the updates I needed and uploaded and installed them. I got a message that indicated diagnostics were being run and that my system needed repair. Thereafter, it completed the updates without incident.

My profuse thanks to you, again.

I was able to use the computer thereafter. In fact, it either turns the computer off so all I need to do is start it again OR it takes me back to the sign in screen.

Thank you.
