In windows you can assign admin access to any account if you wish, kind of like sudo in unix. "Administrator" is a special account, basically like root in unix.
runas /user:Administrator2Sounds dangerous to me.
Specially dimmed background, characteristic sound, the dialog runs on a dedicated desktop i.e. you won’t see any apps nor the start menu. Also the default button is No i.e. you can’t accidentally press Yes with enter or space keys, you have to use a mouse.
