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.

    Hi all,

    This may be of use to some on here trying to solve the 0xC1900101 error - which I had as well.

    What I did to solve it:-

    Ran DISM to check for errors with current windows install - came back fine.

    I then used msconfig with admin privileges to stop all running services apart from Microsoft services,

    and I also then stopped all start up programs from running via Task manager.

    I then tried installing using the iso file and running the setup from the iso.

    I was able to update to build 10.0.22000.132, and once this was installed I then ran windows update

    which updated me to build 160.

    Have not had an exhaustive look/try of the system yet but all seems well. I should add that I had to add a TPM module to my machine otherwise it would not install. For those wondering I have a Intel 5960X cpu and 32Gb ddr4 ram.

    Hope this helps some of you.

    Mark

    By the way, Can I ask smth? Is there any way to download Windows 11 for Legacy Bios. My laptop said that "Your laptop does not meet the minimum hardware requirement for windows 11". Is there any hope for me?

    I didn't realize an ISO was finally available ... looks recent, thanks for the tip! Maybe I'll give that a shot.

    No luck with the ISO. This is nice and confusing:

    I had that too - but press the button to the right - dismiss, and setup will continue. Mine did anyway. You may need to press more than once.

    Hope this helps.
