Generally the Dumbest of Dumb people who call for support. They typically forget their password, id, how to email, how to notice power lights, and sometimes mistake their Pager/cellphone battery being low as a Pc noise. They may call when it says your pc has installed updates successfully also, claiming they are being hacked by an unknown person, unplugs their Speaker for a "fan" then calls support wondering why they have no sound.
"I can't click on the X my pointer will not go down to the keyboard!!!"
