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.

    Yep, update to .160 went fine and then I re-enabled all the stuff I disabled. Everything seems good now ... just have the (expected) warning about unsupported hardware.

    So now I have time to prepare to do a clean install of Win10 once the Insider Preview is done (or else possibly just get a newer NUC).

    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!

    Mine updated ok to latest build 160. Glad you got there in the end.

    Thanks. I tried that but then got the same error eventually, as also mentioned above.
