I like CCleaner it's a nice easy to use tool for the novice but I have noticed that it leaves a lot of stuff untouched I go through manually as well to make sure that things like temp files and cookies are removed and i just see far to much leftover stuff after using CCleaner run another reg cleaner after using CCleaner and it will almost always find more reg entries.
Just curious if anyone else has noticed this all I hear are rave reviews of CCleaner and as I said it's pretty good for the novice but for the more thorough IT type it's just not enough.
