windows 7 - Group Policy Editor restricting my administrator account?

Hi I have created a problem on my PC and now I feel really stupid. I tried to restrict access to certain programs on a recently created standard user account via "gpedit.msc". After completing the list of programs I wanted the particular account to have access to, it has now also applied that to my administrator account. I am using win 7 pro x64.

I cannot access anything except 4 programs that were on the list, everything else I try to do gets denied. I cannot even get back in the group policy editor (gpedit.msc) as I get this error:

"This operation has been cancelled due to restrictions in effect on this computer. Please Contact your system administrator."

I am the system admin, I do not get it? I literally cannot do a thing or open a thing. What do i do? I feel so stupid I've basically locked myself out of my own computer. I followed what it said on this link How-To-Geek.

Please help!!

I was able to find the answer after some searching around, this answer is from this question in Server Fault, posted by San Jac.

I had the same issue by accidentally changing system settings in gpedit. Try this fix I got from Greylox.... It worked for me.

1. Open "Run" & enter %systemroot%\system32\GroupPolicy\User




2. Delete registry.pol (if it exists).




3. Go to %systemroot%\system32\GroupPolicy\Machine
   and delete registry.pol (if it exists).




4. Reboot your system.




5. Log in using your administrator account & create a new administrator account.




6. Reboot the computer & login as under new administrator account.




7. Open "Run" & enter gpedit.msc





8. Go to "Local Computer Policy" → "User Configuration" → "Administrative Templates" → "system" → "Run only specified Windows applications" (as shown below) & disable it.

9. Run gpupdate /force and login with your old administrator account.
