All Cleaner is a very useful program for cleaning up the history of your activities on a computer. Many people do not realize that Windows and other software programs store information about what they have done, what documents they have used, what web sites they have visited, and various other activities they have performed. 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.
