Fix: System Restore Failed While Restoring, Copying Or Mounting The Registry

System restore is one of Windows’s most essential and advanced utilities, allowing you to restore your PC to a previous state. Sometimes, System Restore may fail with an error message—System Restore failed while restoring, copying, or mounting the registry. You may also see errors such as—Restore failed to extract the original copy of the directory from the restore point. You can try System Restore again or choose a different restore point.

Why Does System Restore Fail While Restoring, Copying, Or Mounting The Registry?

Windows Registry is a database. Once system restore has placed everything in place, the last step is to copy the database from the backup and place it with the rest of the files. So when the PC boots, it will automatically use it.

A possible cause of this error is when there is corruption with the files in the System Restore or the Registry itself. For a System Restore to work, numerous components need to work right. This includes the Windows Registry, System files, Windows Appdata folder, and others. If anything fails, the whole process will fail.

Fix: System Restore Failed While Restoring, Copying, Or Mounting The Registry

Here are some of the tried and tested methods that are known to work in fixing this issue. Makes sure to check if the System Restore works after every troubleshooting solution.

  1. Use a Different Restore Point
  2. Replace Corrupt System Files (Using SFC)
  3. Set Volume Shadow Service to Manual
  4. Configure System Restore Disk Space Usage
  5. Perform System Restore In Recovery Mode
  6. Perform System Restore in  Clean Boot State

Let’s look at the detailed steps for all of these methods.

1] Use a Different Restore Point

If the first restore point you try doesn’t work, you can always try to use another restore point. If you see only the default restore point, you must check the Show more restore points option in the bottom left corner of the System Restore window to see more restore points.

2] Replace Corrupt System Files (Using SFC)

As previously stated, corrupt system files can be one of the primary causes of this issue. Windows has an inbuilt command-line utility that allows you to repair corrupt software components and files on the PC called SFC (System file checker). Here’s how to use it:

  • Open Elevated Windows Terminal (With admin privileges) by right-clicking the Start icon and selecting the Windows Terminal (Admin) option.
  • Now, type the following command and hit enter.
SFC /Scannow
  • Since this is a system-wide scan, it takes an extended amount of time. Once the scan, you’ll get the details if SFC repaired any files or folders on your computer (if any).

Once the whole scan is completed, you may try performing a system restore.

3] Set Volume Shadow Copy Service To Manual

Volume Shadow Copy Service is majorly responsible for the functioning of System Restore. It is used to create volume backups which System Restore then uses to restore the PC to its previous state. If this service is off, you may encounter the issue. Setting the volume shadow copy service to manual mode may solve the problem. Here’s how to do it:

  • Open the Run dialog box by pressing Windows+R keys on your keyboard.
  • Now, type Services.msc in the Run dialog box to open the Services window.
  • Once in the Services windows, scroll down to find Volume Shadow Copy and double-click on it to open its settings.
  • In the Volume Shadow Copy Service settings, head to the General tab.
  • Now, find the Startup Type option and select Manual from the drop-down list next to it. And Click OK to apply the changes. Setting Volume Shadow Copy Service To Manual In Windows
  • Make sure to click on the Start button to start the service.

4] Increase Disk Space

System Restore fails because of the lack of storage space on the SSD or HDD. When a System Restore point is created, it takes space based on the number of programs, files, and accounts on the PC. When restoring, it will need a bit more space than the size of the restore point.

It would be a good idea to check the storage space in your system drive or where Windows is installed. You can use File Explorer and Storage Space feature to figure it out.

5] Perform System Restore In Recovery Mode

Some other software like an Anti-virus or any software with control over your System can also interfere with a system restore. You can prevent them by performing the System restore in Recovery mode. Here’s how to do it:

  • Open Windows Settings and open the System Settings from the left pane.
  • In the System settings, open Recovery. Now, you’ll see an Advanced Startup option. Click on the Restart Now button next to it. Advance Starup In Windows
  • Now, you’ll boot into Advanced Startup. In the Advanced Startup menu, select Troubleshoot, then choose Advanced options.
  • Now, you’ll see the System Restore option. Click on it, select the desired Restore Point and proceed with the steps required. System Restore In Avanced Startup

6] Perform System Restore In Clean Boot State

When you boot your PC, third-party services and Windows services start with it too. In a clean boot state, the PC starts with minimal and only necessary services, preventing any other service from interfingering with the System Restore. You can try performing the System restore in a clean boot state to solve issues with the System Restore. Here’s how to do it:

  • Open the Run dialog box by pressing Windows+R keys on your keyboard.
  • Now type msconfig and hit enter.
  • It will open the System Configuration window. Head over to the General tab.
  • In the General tab, check the Selective Startup option and head over to the services tab.Selective Startup In Windows
  • Now, check the hide all Microsoft services option, then uncheck all the services that appear. Disable All Third Party Services At Startup In Windows
  • Now, apply the changes and restart your PC.

Once your PC is in a Clean Boot state, perform System Restore the usual way. Any interference from third-party apps and services will be absent here. It will allow smooth system restoration.
