Performs two useful functions. First it simplifies the process of backing up critical system files from your computer. When a PC crashes is it often not necessary to format and/or restore your entire hard drive. Instead, by restoring the Windowsregistry and other configuration files the system problems can be solved. System Snapshot also has the ability to restore configurations such as desktop icons, wallpapers, and start menu items every time Windows is started. This is ideal if you have public computers where users are constantly changingconfigurations. If a user changes wallpaper, adds icons, etc. and System Snapshot will automatically restore your assigned settings every time Windows is rebooted.
