CCleaner
From the website:
"CCleaner is our 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!"
The features of this application are great. it is one of the first i install on any Windows system i work on. it will clean temp files, registry files and excess restore points. It is a must have for any person wanting to see how much disk space can be saved. I once got rid of over 60 Gigabytes of temp files from one person's machine!
