Windows 7: I've managed to deny myself access to administrating

I've managed to deny myself access to administrating

I've been doing some customizing and in an attempt to give myself permission to rename a file in system32 I ended up denying myself permission to launch anything as an administrator.
I am prompted with the 'File system error: 65535'. If I try to use command promt I'm given some BS on how I don't have sufficient permissions.

Also a note, I do not see 'SYSTEM' in the list of users in system32 properties>security tab, it was there before.
I've given myself full permissions (other than special permissions because it's grayed out) for both my user and administrators. The same is for 'TrustedInstaller' which I do not remember having the same permissions. 'CREATOR OWNER' is the only user with special permissions but no other access.
Please help, I dun goofed.

Another note: Whenever attempting to update security settings for the folder, access is denied.
Edit: managed to bypass the access denied and added the SYSTEM user again with full acces yet I cannot give it 'special permissions', as if I have a clue what they are.

Here are my permissions:
Creator owner: Special Permissions allowed
System: All allowed, no special perms
Administrators: Same
Users: Same
TrustedInstaller: List folder contents allowed, special perms unticked. Was ticked when I got here.
How do I enable the special perms, are they even necessary? What else have I messed up?

Ending this thread, put PC to sleep and when I powered it back on it gave me a black screen and I couldn't even type in my password. Luckily I have W8 too.
