I hate to have to be this frank with you, but I don't think our forums are the right place for your questions. You said:
A) "im grounded, so im sneaking on to try and fix the comp".
B) "I cant do a full windows restore, cause My dad has a program which if deleted he'll have to buy a new one for quite a bit".
I'm sorry, but we aren't here to help people get around those types of restrictions any more than we're here to help people get around installation problems with an illegal copy of Windows.
Judging from what you've posted, it sounds like the computer you've mucked up is not your own personal-use computer, but a computer also used by others in the family. If so, my suggestion is this: if you know that you're really the one who hosed the system, just cop to it and deal; "im sneaking on to try and fix the comp" doesn't really sound like the right solution.
