I have been using CCleaner for years. It is one of the best free ways to speedup your PC. It is one of those tricks that your "friend who makes your computer better" uses. It has a simple interface and is easy to use, don't even need to understand annoying computer jargon.
CCleaner 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! :)
