Disk2VHD error snapshotting volumes - Fixed

When I created a VHD for a Windows 2008 R2 server using Disk2VHD, an error poped up as "Error snapshotting volumes".

I opened the Windows event log viewer and found several errors of VSS.
One of them was Event ID 22 -
Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {79079d5c-ef20-4952-b9fc-cfd443b38641} and Name SW_PROV is [0x80040154, Class not registered].

Run RegEdit and open the registry path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Providers
There was a registry key of {f782463b-33bb-4043-ad8d-60b728d26a6c} that represented as "Acronis VSS SW Provider" and there was a CLSID item of  {79079d5c-ef20-4952-b9fc-cfd443b38641} under it.

The backup software Acronis is no longer installed on the server. After I deleted the registry key of {f782463b-33bb-4043-ad8d-60b728d26a6c}, Disk2VHD worked perfectly.

Hopefully this information can save your time.

    Exact same issue and this resolved my error. Make sure to restart the VSS service after you delete the registry entry.

    Thank you very much for the solution, I had an entry of some Symantic program I had once installed (CLSID {262b716e-bb23-41b5-aaef-e2c15e767167}).
    After removing that one Disk2VHD worked without having to restart the VSS service.

    did not work in me. my computer is neither acronis nor sysmantec. but there is visual studio. I guess it doesn't work because of that.

    This works for me. Thank you! However, my Acronis CLSID is different from yours.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers\{f5dbcc43-b847-494e-8083-f030501da611}]
    @="Acronis VSS HW Provider"
    "Type"=dword:00000003
    "Version"="1.0"
    "VersionId"="{89cdaf20-82b6-42cd-a4b4-573c81999c35}"
