ACA System Restore is a better and easier system restore software. Windows System Restore software only protects system files and some program files--not all data, programs or user settings. Windows System Restore cannot restore your entire system if Windows can't boot up. ACA System Restore protects every single bit of the system and can restore your system even if Windows is unbootable. And best of all, ACA System Restore only takes no hours or minutes, but seconds to backup or restore system.
