Cannot install Windows 11 - Error 0xc1900101

Anonymous

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.

There should be some additional info in the output. Can you log it in Feedback Hub and share the link with me?

Even though people in the Dev track have a lot of advanced skills, needing to jump through these kinds of ridiculous hoops is crazy.

I partitioned my SSD, which was suggested by another fellow windows insider. I installed Windows 11 in that blank partition, and now I am up and running.

I had to reinstall all of my applications (all from Microsoft by the way) and move 750gb of files and folders.

Would I do it again to get windows 11? Without cussing, I would say no!

Same error with build 10.0.22000.132.

The 0xc1900101 error is generic. There isn't a single answer to resolve it. You will need to run SetupDiag (see above) to determine what is causing it in your specific case.
