Desktop Spy 4.0 secretly takes pictures of your computer screen, records all applications loaded, web sites visited, chat conversations, E-mail activity, and anything else that is visible on the screen. You can take pictures of the entire screen or just of active Window and save the pictures in high quality or low quality JPEG format. This program could be useful for parents who want to know what their children are doing on the Internet or employers concerned about inappropriate use of company PCs. Screenshots can be taken many times per second, if your computer can go that fast, or as infrequently as once every few minutes or hours. Screenshots can be played back like a slide show, displayed frame by frame at the speed you choose. Desktop Spy 4.0 has many built-in features to save processing memory and disk space. You can also set a password to this program to prevent other people from using it.
