You find the driver: Device Manager > System devices > ASUS System Control Interface v3
You must prevent Windows Update from automatically reinstalling the above driver, or else you will get the 0xc1900101 code again. See below
Prevent Windows Update to automatically install the ASUS driver:
Win + X
Select "System"
Under "Related settings" select "Advanced system settings"
Click the tab "Hardware"
Under "Device Installation Settings" click "Device Installation Settings"
Select "No" to prevent the automatically download of manufacturers apps...
Delete the driver under Device manager
Restart the computer
Try again to update to Win 11.
