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.

    The following information may or may not be useful regarding the 0xC1900101 error. On one of my attempts to upgrade my windows 10 it failed with the same error, but after the roll back and subsequent re boot I had the following message on screen.

    We couldn't install windows 11. We set your pc back to the way it was right before you started installing windows 11.

    0XC1900101 - 0X4000D

    The installation failed in the second _Boot phase with an error during Migrate_Data operation.

    I hope this may be of use to someone in figuring out what is causing this.

    Did you try installing from iso after a clean boot as mentioned previously - stop all services other than Microsoft, and programs in start up? This is what worked for me.

    I thought I had, but I checked and missed a service or two, so I tried again, and it worked! So I've got 21H2.22000.132 running, now to see if Windows Update will update to 22000.160 and then I can try re-enabling all the stuff I turned off.

    Thanks!
