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.

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.

    Dear Ramesh,

    After doing the clean boot, the Win11 setup disappeared on windows update.

    I am now trying to install from the Windows website.

    Hi Christopher.

    It disappears after some failed installation attempts and will reappear after a few days.

    Anyway, ISO is the preferred method.

    1. Download Windows 11 Media Creation Tool (MCT) from this link:

    https://go.microsoft.com/fwlink/?linkid=2156295

    1. Run MCT and download the ISO it recommends for your system. Do *not* uncheck "Use the recommended options for this PC".
    2. Right-click on the downloaded ISO and choose "Mount." This assigns the ISO a drive letter.
    3. Run setup.exe from the ISO drive. This starts the in-place upgrade/repair installation.

    (Your files, settings and applications will be preserved if you use the ISO recommended for your system by the Media Creation Tool.)
