Registry Restore 2000 is a Windows backup utility. It's main focus is on backing up the Windows Registry which is considered to be the most vulnerable component in the Windows operating system. It also makes backup copies of other pertinent system files such as: the Autoexec.bat, Command.com, io.sys, msdos.sys, system.dat, user.dat, as well as every .ini file in the windows\system folder. It even exports a copy of the registry.
