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.

So, I have no more options.
Tried:
.iso (no option to keep apps), fresh installation is a success, though. (but i prefer to keep apps).
Rufus 4.6 offers to keep apps, but fails
Please start a new thread and share the setup logs there.
The following batch file collects the setup logs and saves the zip file to your desktop.
Download setuplogscollect.bat and run it as administrator.
https://winhelponline.com/files/setuplogscollect.bat
Right-click on the downloaded file and click Properties. Click "Unblock" and click OK.
Right-click on the file and choose "Run as administrator"
It outputs a SetupLogs.zip file on your desktop.
Share the file on OneDrive and post the download link in the new thread.
