This tutorial will show you how to enable automatic backup of the system registry to the RegBack folder when the computer restarts in Windows 10 and Windows 11.
Starting with Windows 10, version 1803, Windows no longer automatically backs up the system registry to the RegBack folder when the computer restarts, and creates a RegIdleBackup task to manage subsequent backups. Windows stores the task information in the Scheduled Task Library, in the Microsoft\Windows\Registry folder. The task has the following properties:
If you browse to the \Windows\System32\config\RegBack folder in File Explorer, you will still see each registry hive, but each file is 0 kb in size.
This change is by design, and is intended to help reduce the overall disk footprint size of Windows. To recover a system with a corrupt registry hive, Microsoft recommends that you use a system restore point.
If you have to use the legacy backup behavior, you can re-enable it, and then restarting the computer to apply.
