It really could only possibly be of benefit to those still running Win98, and even then the benefit is highly dubious. For the other 99% of us that are using Win2000 onwards, the Registry is handled in a far more sensible way and the risks of messing about cleaning stuff out is just not worth it. All you get is a tiny amount of disk space saved and no performance improvement at all.
