This program is called "CCleaner". It is a FREEWARE system optimization, privacy and cleaning tool. 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.
Additionally it contains a fully featured registry cleaner. But the best part is that it"s fast (normally taking less than a second to run) and contains NO Spyware or Adware! :)
