CCleaner is a utility program that I've used for many years. It cleans out your PC of useless junk that tends to accumulate over use of your computer. It can be downloaded at Piriform.com website. I've used this on a variety of Windows based operating systems and have rarely had any problems. There is a paid version but the free version works quite well and is a relatively small download and won't clog your machine up. This tutorial is fairly simple and to the point.
