Is there any way to get into the administrators account?

Thats naughty!

The easiest way is to peek when they are typing in their password. The other way is to somehow get an Administrator to log into a computer (say, to fix it) and then create a diversion (say, exploding computer in another room). Hopefully the admin will rush away without locking their machine and then you can give yourself admin access. Make sure you create a few other accounts and give them admin access as well in case you're caught and they delete your account. Don't get caught however, you'll be banned from using the computers for the rest of your school life.

Lol. When you boot up the computer, and it has a log in (or you may need to just log off the computer), hold down clt + alt + Delete all at once and push it twice in a row. It will bring up a log in box. Type in Administrator in the username box... Then you will have to figure out what the password is. You can just hit enter with it being blank, and if there is not a password, you will be in...

have a word with the administrator and ask him what his password is
