When Win 7 Pro boot up to login screen, I only can see the users. but at this point, if I need logon as administrator, what can I do? I know Windows XP, I can hold "Ctrl" + 'Alt" and press twice "del" key to bring up a login screen let me to change username.
I tried same with Windows 7, but didn't work. maybe this is a simple question. but I am new to Win7.
