Microsoft used to perform backups of the registry automatically, but the feature has been quietly disabled in Windows 10. If you want to regularly backup registry to RegBack folder, you’ll have to manually enable Registry backup feature in Windows 10.
Windows 10 version 1803, version 1809 and the latest version 1903 do not back up the registry automatically. The lack of registry backups in Windows 10 isn’t a bug and it has been introduced to reduce the overall disk space footprint of the OS.
At the moment, the RegBack folder is either empty or contains multiple registry hive without any content. The Redmond giant recommends Windows 10 owners to use system restore point instead of the traditional registry backup system, but you can still force the system to utilize traditional registry backup functionality.
In this tutorial, we’ll walk you through the steps to automatically backup Registry to RegBack folder (Windows\System32\config\RegBack).
To enable automatic Registry backup in Windows 10:
- Open Start menu.
- Search ‘Registry Editor’.
- Browse to the following path:
HKLM\System\CurrentControlSet\Control\Session Manager\Configuration Manager\
- Right-click in the right-pane.
- Select > New > DWORD (32-bit) Value.
- Set ‘EnablePeriodicBackup’ as a name.
- Double-click EnablePeriodicBackup entry.
- Change the value to 1.
- Click ‘OK’.
After editing Windows Registry, reboot the system to apply the changes.

Changes to Windows Registry
As mentioned, Microsoft has confirmed that the lack of registry backups is intentional to reduce the overall disk space footprint of Windows.
Instead of legacy backup, Microsoft recommends users to maintain Windows 10’s system restore points and use it to revert Registry changes.
A damaged Windows registry can also cause boot failures and other critical problems. In such a scenario, a system restore point would be more reliable than the traditional backup feature.
