A lot depends on:
a. the power of the cleaner, how deep it looks.
b. how user friendly it is, e.g. do you need to understand the workings of the registry and does it provide a help file, etc.
c. does it classify the results in a form of say, safe to fix/remove, should be OK or you could get burned if you touch this, etc.
The one I use is quite powerful, doesn’t have a help file, not particularly user friendly, but it does present the results so that you can select by traffic light colour, Green = safe, Amber = care, Red = Don’t touch unless you really know what you are doing. But I like it, it is called RegSeeker, however, I wouldn’t recommend it to someone who doesn’t know there way around the registry.
