I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101 after rebooting.

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.

Windows for home | Windows 11 | Windows update

Dear Ramesh,

Thank you for your assistance, you were really helpful.

At a point my pc touch screen stopped responding during the many installation attempts, so didn't know what I had done to cause this. then I decided to clean install, so i chose not to keep my files and settings and it worked.

    Hi Christopher,

    Please clean boot the computer. A clean boot is the process of starting Windows without loading third-party apps and services. Please see this Microsoft article for more information.

    How to perform a clean boot in Windows - Microsoft Support:

    https://support.microsoft.com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd

    (Step 3 is very important. You need to first enable "Hide all Microsoft Services" before clicking "Disable all".)

    Once done, re-run the Windows 11 setup. Post fresh logs if the setup doesn't succeed.
