    Update to Windows 10 21H1 rolled back. Where is the error?


    I have a system running my home automation. I want to install Windows 10 21H1 on it. It starts installing and everything looks good. It reboots and continues with the installation. Then after several hours I check the system again and it is logged in and back at 20H2.How can I find out what went wrong? From there I can then see how to solve it.

    :)

    Update to Windows 10 21H1 rolled back. Where is the error?

    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?

    Windows 11 is awful. Where is the option to roll back to 10?: I tried 11 upon first release and it was awful.
