During upgrading from Windows 10 to Windows 11, the installation fails with error 0xc1900101.

The upgrade was launched using Windows 11 Installation Assistant.


I found out that the upgrade to Windows 11 fails because I had Google Drive for Desktop installed and running.

The problem is that latest Google Drive for Desktop adds an actual drive (e.g. G:) and it causes problems with the upgrade.

Solution: Quit / Disable Google Drive for Desktop before upgrading.
