How To Backup Windows Registry Automatically (Scheduled Backups)

Windows Registry is the most important yet the most sensitive and delicate component of Windows Operating System. The Registry is a database which contains all the settings and configurations of the Operating System and application software.

Since Windows Registry is very important, it should be backed up regularly in order to save yourself from unexpected disasters. In most cases where Windows crashes, restoring the Registry to a prior date will fix the problems.

If you are using the Windows Registry Editor, you can easily export the whole registry database to backup the Registry. But this work has to be done manually and regularly. Windows does not provide any way to automatically backup the Registry on regular intervals except with System Restore.
