    Unable to update Windows 10 to 21H1


    I have two machines both running Windows 10 Pro. Both were on 20H2 prior to updating. One machine updated flawlessly although it took a long time. It is now on 21H1. The other machine gives me an error after quite a long time into the update process. I attached two screenshots of the error. I do not want to call Microsoft because they have been less than helpful in the past. Any suggestions?Unable to update Windows 10 to 21H1-windows-10-failure.jpgUnable to update Windows 10 to 21H1-windows-10-failure-code.jpg

    I followed the directions although I did not see any way they would make any difference. But I was mistaken. The update worked after following your instructions. Both my machines are now at 21H1.

    Thank you!
