I've reset local Administrator's password, but after re-boot, on the Welcome Screen, I do not see the Administrator user, just list of regular users. I have Windows. How can I log in as Administrator?

The Windows Operating System when booting, only displays names of regular users on the Welcome Screen by default.

The Administrator's account is hidden. Press the combination of [Ctrl]+[Alt]+[Del] two times to display the Login Dialog Window and you will be able to type both user name and password.

Type "Administrator" and use an empty password.

Please change your password of your regular user immediately after login in.
