If anyone remember this tool used to be called crap cleaner and when you clicked on the button it used to make a flushing noise... I miss that! Anyway my first tool is ATF cleaner which removes other profile trash as well then I run CCleaner as a secondary only because after ATF, ccleaner runs way fater especially if you get a system that has never erased a cookie of prefetch item since its birth. Good stuff to run even before troubleshooting.
