Microsoft has stopped automatically backing up all registry entries for Windows 10 systems since last year

According to Microsoft, the company actually stopped the previously implemented automatic registry backup strategy as early as Windows 10 Version 1803. The automatic registry backup policy was originally designed to prevent accidental conditions from causing registry corruption, so the system periodically scheduled automatic backups can be recovered in case of an accident. However, it seems that if the automatic backup of the registry automatically takes up a lot of hard disk space, Microsoft decided to stop executing the automatic registry backup policy.

Microsoft said in the support documentation that the system no longer automatically backs up the registry to the RegBack folder since Windows 10 Version 1803. So now when the user accesses \Windows\System32\config\RegBack\, you can see the individual configuration units but each file is 0kb.

Turning off the automatic backup policy can help improve the capacity of the hard disk space and reduce the occupation. Of course, if the user needs it, the backup function can still be enabled. Microsoft recommends that you use the restore function to restore when you encounter problems with the system restore function.

For those who understand the registry and have the ability to adjust and restore the registry themselves, you can also restore the automatic backup strategy according to your actual needs.

Open the Registry Editor and go to the “HKLM\System\CurrentControlSet\Control\Session Manager\ConfigurationManager\“ registry path, create a new folder EnablePeriodicBackup, new REG_DWORD key value. Modify the REG_DWORD key value to 1 to enable it. After restarting the system, the system will automatically add a regular registry backup plan in the scheduled task management.
