That's ok, I just thought you meant a normal administrator account.
I found this below that you might see if the 4th post may help you with this as well.

I had the same problem trying to edit CurrentControlSet/Enum/USB. I tried all sorts of permission and ownership changes without success. I finally got it to work by using the following command
psexec -i -d -s c:\windows\regedit.exe
psexec is available from Microsoft here

This gave me full access to the registry. You should definitely be careful with this sort of access.
For me, my USB to serial device wasn't working any more. I wanted to remove the registry entries for it in Enum/USB. After deleting them with the above method, I plugged in the USB to serial adapter and it started working again. I'm running Win7 PRO.
