Shutdown any pc on network of school or college

ok i found that if you have someones login for school that is relatively stupid use that so that they dont get in that much trouble because they are ruled out as a major cause what you do i get their login and pass secretively so you can get away scott freeok onward go to the notepad type in shutdown-i and save as and save it as a bat file close it open it and type in the school number (ask like a tech guy at the school) then the room nunber then the computer number and when your done shutting down computer delete the file and empty the recycling binhave fun i do it all the time lol
