Download CCleaner 2.04.543 - filehippo.com
Honestly an excellent tool that won't just clean temp files but history, MRU's, Prefetch Data and many more. It also has a registry cleaner to clean out your system registry for a bit more speed
And you can control what it removes so it's very flexible (but i have mine set for it to clean everything). And probably the best party, it takes a few seconds to a few minutes at the most (heavily clogged pc's)
