I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101.

The installation starts, and after a couple restarts, it says:

" Attempting to recover installation "

" Undoing changes made to your computer "

And then I am greeted with error 0xc1900101 on Windows Update.

Windows for home | Windows 11 | Install and upgrade

    Hello, I tried the procedures that you described on troubleshooting, but the same error occurs. I have made a copy of the log files that are mentioned and a screenshot of the profilelist of the registry. How can I send them so someone can review them should I post the LINK HERE? Or to a personaL address of a tech support individual?

    Hi Chris,

    Please post the link to the log files i.e. Setupact.log first so that I can have a look and suggest. It might not necessarily be related to the user profile. I would ask you for regedit screenshot if required. The log files can be put on Onedrive and then a link can be shared in the next reply.

    As soon as you reply, I would split your post to a separate question.

    There is not only one way to install Windows 11!!

    You can download a iso file from microsoft Download Windows 11 (microsoft.com)

    after downloading the iso file, mount it then copy all the files inside to a bootable USB then what u have to do is go to settings go to recovery and then advanced then press reboot now

    then ur pc should reboot and have a blue screen press troubleshoot and then press command prompt then type in ur bootable USB (Example: D:)

    Then type setup and then follow the instuctions to install windows 11

    My last attempt on April 19th 2022 was successful as my reply indicated above. There is no need for me to provide logs I think.
