Most likely the issue with Sp2 for XP it really messed up permissions in registry that prevents files from being deleted. Try downloading dial-a-fix and running repair permissions than see if it is not able to be cleaned. I run it periodically because windows really removes alot of permissions on window updates, ect and I will find many of the CLASSES keys protected once again.
