You can save the system configuration on Windows 95/98/ME with this small tool. It creates a backup of the registry and some important INI files, and you may define additional files it should copy. All settings are saved so you have to click only once when making a backup.
On Windows NT/2000/XP/Vista/... you CAN'T USE this tool anymore. Please use the appropriate equivalent that comes with your operating system.
