My school security is shit, so tell me, how did you do it? They didn't even block cmd, they don't block anything....
*EDIT* Nvm, I just red ^^ it, but it doesn't let me, says I don't have the privilages.
+Everyone in my school has their own username, I think the reason you got caught was because when you hacked in the admin account, they tracked you down, that why, I'm gonna use my friend's account, which he doesn't know :p, default password is 12345 so it pretty easy to get in.
