A friend of mine has had her computer for 4 years, and as we know things tend to get a little sluggish. Someone suggested to her she clean out her registry and defrag, and while she did the second one no problem on her own, she isn't sure which application to use.
Any suggestions for a Vista registry cleaner? Also, any way for her to revert her changes (a restore point) in Vista? XP guy here so I have no experience with Vista.
