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.

    After turning on, the windows update was unable to download. clicking on pause updates for a week and then resuming updates helped in solving the problem.

    Same issue for me, have tried multiple times a month apart to try and let Microsoft make updates, system is saying it's ready but get that error every time trying to install. I tried removing third party anitvirus software temporarily prior to install, but makes no difference. PC is more than capable (i7-1165GY, 16GB Ram).

    Yes, we need a better answer than an error code. Why did the system generate the error code!!!
