CCleaner Free

CCleaner is a freeware system optimization and privacy 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. But the best part is that it's fast (normally taking less that a second to run) and contains NO Spyware or Ad-ware!

CCleaner was designed from the ground to be safe and secure to use. It has multiple levels of checks in place to ensure that it cannot delete any useful information or documents you may still need.
