|'I had trouble with a reg cleaner before and prefer not to do that'|
But I'm sure you never tried this one I mentioned. It is a real user friendly software that almost anybody can use easily, plus it backs up everything you remove. I also use Ccleaner, but this one lists all the progs etc and if you don't understand it, you can google the questionable files.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
