What is the best free system cleaner out there?

I've got ad-aware, had system mechanic, norton systemworks and most other packages out. I was just wondering if anyone has just one good free program that does the job. Thanks

I would suggest you go to WINDOWS CATALOGUE. There are some excellent free programs, i.e. REGCLEANER. I use it and it works very well.
Hi, I have tried windows registry repair pro, it says it only removes 15 problems, but i have found that if you keep clicking repair and clicking no to the box that pops up, it removes 3 other problems at a time, type windows registry repair pro into google and click on the 1st result and download it
AD-AWARE IS ONE OF THE BEST FREE ONES BUT IF U WANT SOMETHING MORE COMPLETE THEN YOU SHOULD CONSIDER SPENDING A SMALL AMOUNT OF MONEY £10 OR £20 SHOULD COVER IT. YOU MIGHT WANT TO TRY SPYBOT
CCleaner works great. It really thoroughly cleans out all the old junk files on your computer. Very popular.
Ive tried them all ,and cant find better than spyware doctor.
Ive found beclean, free , fast, effective, and easy to use, hope this helps.
