Way 2. Copy the Required Registry Files

If the error persists after re-registering the Volume Shadow Copy Provider or VSS DLL file, some keys may be missing in the Registry on your Windows 11/10 computer. In this case, you have to copy the missing registry keys from another healthy computer to your computer. Before modifying the registry, create a system restore point.

Step 1: Press the Win + R key to open the Run dialog box. Then type regedit in the Run box, and press Enter to open Windows Registry Editor.

Step 2: Copy the following path into the address bar of Registry Editor and press Enter.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers

Step 3: Under the Provider key, you will see the subkey {b5946137-7b9f-4925-af80-51abd60b20d5}. It should contain the following values on the right side.

• String Value – (Default) with the Value data Microsoft Software Shadow Copy provider 1.0.
• DWORD (32-bit) Value – Type with the Value data 1.
• String Value – Version with the Value data 1.0.0.7.
• String Value – VersionId with Value data {00000001-0000-0000-0007-000000000001}.

Step 4: Under the {b5946137-7b9f-4925-af80-51abd60b20d5} key, you will see the CLSID key, and it shows the (Default) String Value with the Value data {65EE1DBA-8FF4-4a58-AC1C-3470EE2F376A}.

Step 5: Open another healthy computer and navigate to the above path in Registry Editor. Now, export the same registry subkey from that computer and move the key to your USB flash drive. In our example, the subkey is {b5946137-7b9f-4925-af80-51abd60b20d5}.

Step 6: Connect the USB flash drive to your computer and double-click the registry file exported from the healthy computer. Click Yes to merge the registry file into your registry.

If the subkey {65EE1DBA-8FF4-4a58-AC1C-3470EE2F376A} is the same on your computer and its value is missing, you can also create the above value manually.
