CCleaner
(Crap Cleaner) is a freeware system optimization, privacy and cleaning tool. Additionally it contains a fully featured registry cleaner. It removes unused files from your system allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it’s fast (normally taking less than a second to run) and contains NO Spyware or Adware!
