  • For people who come across this issue.There is missing data for Type in registry

    HKLM\Software\Microsoft\MMC\Snapins\FX:{8b6499ed-0241-e032-6508-da4b1c879d7e}\Type.
    The value for missing data should be
    Microsoft.UpdateServices.UI.SnapIn.Common.SnapInManager, Microsoft.UpdateServices.UI.SnapIn, Version=3.1.6001.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35
    That's how I got mine working again.
