Microsoft explained in the support document: "SinceWindowsStarting with 10 Version 1803, Windows no longer automatically backs up the system registry to the RegBack folder. If you access the Windows System32 config RegBack path in Resource Manager, you can still see various registry configuration units, but each file has a capacity of 0 kb."
If you still want this feature to take effect, users can re-enable it by modifying the registry. The specific operation steps are as follows:
1. Open the Start menu
2. Search for "Regedit Editor" (Registry Editor)
3. Browse to the following path: HKLM System Current ControlSet Control Session Manager Configuration Manager
4. Right-click right side panel
5. Select New
6. Name it Enable Periodic Backup
7. Double-click Enable Periodic Backup, and then change the key value to 1
8. Click OK
After restarting the device, Windows backs up the registry to the RegBack folder and creates the RegIdleBackup task process to manage subsequent backups. Although backup is possible, restoring the registry is not as easy as accessing it.PureTechInfo providesThis article.
