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.

    What Known Issue are they fixing?

    The OP's issue goes back to June.

    Hi CK,

    That's a problem with this tread, most posters don't list their build number.

    We know this is a known issue updating Dev but can happen if they are trying to update from other builds.
