Just in case there are people here who use this instead of ccleaner (surely not!!)
CCleaner looks very good in those comparison charts.
I haven't used that program in years, and frankly don't miss it either.
I use JV16 P/Tools alongwith RegscrubXP and Ccleaner have found JV16's registry cleaner to be not too aggressive and yet very good at what it does, it has in the past found entries which neither of the other two have and this combination of software use has kept my registry very tidy!
