I have MPG/MPEG thumbnail preview support in file explorer on Windows 7. But on Windows 10 file explorer there is no thumbnail preview. Can somebody tell me, is the thumbnail preview I am experiencing on Windows 7 native or did I install an application somewhere along the road to get this functionality? Does this have anything to do with native DVD playback which is available in Windows 7 having been stripped out of Windows 10? On to the solution, is this a known bug or something Microsoft is working on? Or is this now the responsibility of a 3rd party software installation?
