I was able to resolve the issue.



Pressing shift button and restart took me to the screen where it gave you the option to choose the "Troubleshoot". I clicked on the Troubleshoot > Advanced...

Thank you for the advice.

As I can not login, I can not revert the system configuration.

Pressing Ctrl and entering the password did not work. Is there any other option I can try?

Your help...

After I configured to start up the Windows 10 with the safe mode as following method for uninstalling a software, it does not prompt to enter a password at login screen anymore.

It was working...
