You can use any of these to run Sandboxed versions of your programs. If you have installed Sandboxie, you will see the icon on the desktop, start menu and system tray. Some programs may not work with Sandboxie if you try to install them directly inside the sandbox. You can run any program that you have installed in Windows inside Sandboxie this also works with portable apps and regular files (that open in other programs). In fact, I would recommend beginners skip the UI and use the tray icon. You don't even need to familiarize yourself with the interface to use the program. In other words, you will learn how to use Sandboxie for browsing securely, downloading files and recovering them, and installing/running programs inside the sandbox. We are not going to discuss that here, rather we're going to look at the basic usage of the program. Recently Sophos announced that Sandboxie is now freeware, and are planning to make it open source. Sandboxie has changed hands twice I think, from the original developer to Invincea, who were in turn acquired by Sophos (and there are rumors that Sophos is up for sale as well). The activity of the sandbox don't affect Windows or your other programs/files in any way what happens in Sandboxie stays in Sandboxie.
