How to enable Automatic Registry Backup in Windows 10
Starting in Windows 1803, Microsoft has turned off the automatic registry backup feature by default, so the operating system doesn't create automatic backup copies of registry hives any more. Here is how to re-enable this feature in order to have a working copy of Windows 10 registry.
Starting in Windows 10 version 1803, known as 'April 2018 Update' and 'Redstone 4', Windows doesn't create backups the system registry automatically to the Windows\System32\config\RegBack folder.
In Windows version 1803, the OS creates empty backup files. The files represent each registry hive, but each file is 0kb in size.
In Windows version 1809 and above, the files are missing.
According to Microsoft, 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.
In previous Windows versions backup copies were automatically created by a special scheduled task. In Windows 8 and above, the task was included in automatic maintenance.
Thankfully, there is a way to restore the classic behavior and make Windows backup the system registry automatically.
To enable Automatic Registry Backup in Windows 10,
- Open the Registry Editor app.
- Go to the following Registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Configuration Manager
See how to go to a Registry key with one click.
- On the right, modify or create a new 32-Bit DWORD value EnablePeriodicBackup.
Note: Even if you are running 64-bit Windows you must still create a 32-bit DWORD value.
Set its value to 1.
- Restart Windows 10.
To save your time, you can download the following ready-to-use Registry files:
The ZIP archive includes the undo tweak.
Finally, it is possible to backup the Registry hives manually with the built-in console reg command. This will allow you to have the backup files in a folder other than
Windows\System32\config\RegBack. Let's review how it can be done.
Backup Registry Hives Manually
- Open an elevated command prompt.
- Go to the folder where you want to store your registry backup using the
cd /d c:\data\winaero\regback.
- Type the following commands one after another:
- REG SAVE HKLM\SOFTWARE SOFTWARE
- REG SAVE HKLM\SYSTEM SYSTEM
- REG SAVE HKU\.DEFAULT DEFAULT
- REG SAVE HKLM\SECURITY SECURITY
- REG SAVE HKLM\SAM SAM
- Now you have the hive backup files under the custom folder, which is c:\data\winaero\regback in my case.
Disabling the automatic registry backup is a very unpleasant move. Often, restoring the Registry is the only way to get back a corrupted Windows setup working without reinstalling.
I strongly recommend you to create Registry backup copy automatically or manually, whatever is suitable for you.
Also, the size of Registry hive copies is far less than the size of Store apps. Windows 10 and/or its Store includes fairly huge apps like Solitaire, Candy Crush, Calculator and other big preinstalled UWP apps, so it is strange to see an emergency feature being removed instead of getting optimizations done to the Universal Windows Platform.
