Check out 'Ashampoo WinOptimizer'. It's one of those tools similar to ccleaner. I remember using it way before ccleaner was around. It's better than ccleaner in many ways.
It's a commercial app for about $50.00. It's what i use on all my Windows machines.

Interesting, although for 50 bones I wish it did a few more things that couldn't be done for free with ccleaner and a few other tools. The windows customization features look nice though.
