I have read you post several times. You say you changed a guest account to admin. account.
Use that new admin. account to make your needed changes.

How did you make this change? There's not a way I've ever seen to change the name or status of the Guest Account which is preset in Win7 to have no ability to make changes.

What I would do is System Restore to a point before you made these changes.

If this doesn't work you can Enable Built-in Administrator Account from within Win7 or if necessary How to Enable the Built-in Administrator Account from WinRE from the Win7 DVD or System Repair Disk.

Then create an Owner's Admin-level account to use or a Standard User account to use, change the Guest account back, then hide the Built-in Admin account.

If the Guest account has been otherwise modified and can't be reverted by these means then I would run SFC /SCANNOW Command.
