Hi Frank,
This typically happens in two scenarios:
- Your computer got logged in a temporary account.
- Your PC has another drive which has Windows, and PC booted from it.
Let us try to remove the update:
Please open the Windows Recovery environment using either of the steps below:
On the Lock Screen, Press and hold the Shift key. Then, click the restart button on the lock screen located at the bottom right situated in the Power menu, to open the Windows Recovery options.
If you cannot reach the Lock screen or start your computer, restart your PC two times when the boot screen is shown. If your PC has no restart button, press and hold the Power button until the computer shuts down. Do this twice.
The third time, the Windows Recovery options should open automatically.
Choose the Troubleshoot option.
Select "Uninstall Updates," then choose either "Uninstall Latest Quality Update" or "Uninstall Latest Cumulative Update." CHoose the former option. If it does not work, choose the later.
Allow the process to complete.
I’m eager to hear back and work together to find a solution.
