Uninstalled Java and LimeWire. Removed 2 Java Maps (C:/ and D:/) that contained Java 1.42.0_2 still. But then...

I typed 'regedit' into Start/Run and it says: "Registry editing has been disabled by your Administrator".

First off, I AM the Administrator.

Second, I disabled Remote Registry in the Services in my Administrative Tools in my Control Panel and still it says so (It's on again now, just for safety reasons).

Third, I have a Registry Cleaner (Program), should I use that perhaps?
