If you use Tweak UI from microsoft, there is an option that allows you to log in under a user. Alternatively, you can use the registry key. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] set DefaultUserName, and DefaultPassword To fix the problem with the Administrator showing up on the welcome screen, you need to create another Administrator. Seems kinda stupid. I would make another one, and disable the main one. Then make it so the other admin isn't shown on the welcome screen. To keep it off the Welcome screen, you can use Tweak UI again, or the registry key. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList] put the username and a value of 0 in.
