Sometime your computer can crash or give errors that cannot be repaired due a virus or extensive use. If you have important data or simply if you have many installed applications, is important to have a backup to be restored very fast. This will save your time.
Windows has built in an option that automatically create backups at specific intervals, for drive C:, where operating system is installed. In this way, if computer is damaged, you only restore a backup from a previous time and will have back your Windows operating system and all installed programs.
