Backup Registry Hives


That's documented on the internet quite widely, making use of the now non-functional Regback feature. Requires a live boot disk of course.

I've used it a couple of times on tenforums; exclusively for the case where a user's registry is suddenly corrupted, PC unbootable, System Restore unavailable, and user has no disk images.

Example: (these include this basic copy from backup and more)

Backup Registry Hives


As many of us knows that latest version of Windows 10 won't backup registry hives which could be needed when Windows 10 won't boot because of registry errors.

I have created batch script for backing up registry hives this batch script will create two folders at root of C: partition and stores copies of registry hives. The folder named Registry_Backups will contain newly created registry hives and previously created copies of registry hives, these previous backups will have OLD extension. The C:\Registry_Backups\RegOld folder contains previously created registry hive files with OLD extension. This batch script can be schedule to make backup copies of the registry hive files at any given time, i have setup a schedule to make sure my registry hives are backup at logon time.

Execute the batch script with administrative privileges.
