Maybe you don’t realize that Windows and other software programs store history about what you have done, what documents you have used, what web sites you have visited, what images and movies you have seen, and various other activities you have performed. All these history are stored in your hard disk. The Windows built-in functions will not protect you, most of the history can not be deleted with them. Therefore, anyone else can see what you have been doing on your computer, which raises several privacy concerns. Furthermore, much of your activity information takes up valuable disk space, and recovering this space can be very beneficial.
