Ah well, I don't remember what exactly it was that damaged my XP install a few years...all I can remember is that it had a 'reg' as part of the name and it was one of the more 'popular' registry cleaning utilities of the time (~ 2003-3004) 
IMHO, I am not sure if cleaning the registry provides much (if any) benefit. I personally feel that avoiding the installation of unnecessary programs helps to keep the registry 'clean' in the first place.
I have used CCleaner for disk cleanups..it is really excellent for that purpose..but I don't have the courage to let it touch the registry
