Well that's the most round-about way of starting the registry. lol.
You could also simply go to Start | Run and type regedit in the run command line. Does the same thing but does it faster w/ fewer mouse clicks.
Editing that Run registry key isn't going to solve this problem most likely. I suspect a system file has become corrupt or it may perhaps be spyware/virus related.
Since you're running XP, you could try 1) restoring the PC back to a known good working point. or 2) type SFC in the run command line. Also have you done a full virus scan of the system?
