As a bonus it talks to you as well

Ccleaner is a system optimisation tool, very good as you say, be careful re the registry part of it to the OP, if it thinks a registry key is bad when it's actually needed and you go and remove the suspect keys you will be in trouble, (This applies to anything where the registry is concered)! If you do always create the suggested backup when prompted!
