Changed file permissions now cant change them back

Hello i am running win 7 ultimate x64 and have this major problem, here is what i did:
i needed to pawn my laptop for a short time and didnt want my files to be viewed by anyone while it was not in my possesion, so what i did i changed the file permissions of my c: drive so that only admin had fulll control and no one else. well now i cant access my c: drive with my admin accrt. nor will it let me change the file permissions either. also a hand full of other things will not work such as the internet explorer icon on the task bar or start menu but i can open i.e. from the recently viewd submenu from the i.e. icon on the start menu. also i can open files on my c: drive from any old shortcut icons i had left on my desktop but i cant acces them directly from explorer. so i found some work arounds but really need to get full control of my h/d. thanks for the help!

Administrator = the Administrator account - Unique (S-I-D) based permission
AdministratorS = standard (S-I-D) based group

Hello win7KidnapymyHD, and welcome to Seven Forums.

You may be able to do a system restore at boot using a restore point (if available) dated before you made these permission changes to undo them.

Hope this helps,
Shawn

He just saying that these two mean two different things in the list of users and groups in the permissions box.

Administrator = A specific user account. The built-in Administrator account.

Adminsitrators = A group. This includes all administrator acccounts.
