I just find a good statistic of Registry repair software from toptenreviews.
It shows that Advanced System Optimizer is the best and highly recommended..
If you think this tools good or not you can comment at this blog..
I prefer a windows optimization program that actually **tells** you what is going on in a language you can understand. Jv16 Powertools (macecraft.com) does exactly that because it isn't cryptic like all the other. And it's _the_ answer to all my computer problems. You need to try it.
