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.

    1. Please share your setup logs as mentioned below.

     

    • Open the "C:$WINDOWS.~BT\Sources" folder.
    • Select the two folders, "Panther" and "Rollback" (if present).
    • Delete the GenuineTicket.xml file in the Panther folder.
    • Copy the two folders to the desktop and Zip them.
    • Upload the zip file to OneDrive and share the link here.
    1.  Run the Farbar Scanner and share your logs.

     

    Download Farbar Recovery Scan Tool 64-bit (FRST64.exe)

    https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

     

    Note: If Microsoft Edge or Chrome mislabels the Farbar Scanner executable as PUA/malware, choose to keep it by tapping … in the bottom bar, choosing Keep, and then choosing Keep anyway in the dialog that appears. See this screenshot: https://learn.microsoft.com/en-us/deployedge/media/microsoft-edge-security-download-interruptions/dowload-was-blocked.png

     

    If the OS language is non-English, rename FRST64.exe to FRST64English.exe.

     

    Run the program. Don't check or uncheck any options. Click "Scan".

     

    Zip the two logs, FRST.txt and Addition.txt, upload them to your OneDrive and share the link here.
