Windows Explorer no longer shows video previews in Windows 7
I run a 64 bit version of Windows 7 Home Premium. I know that it used to show a preview of all videos in the thumbnail, but now for some reason I only get the file type icon in the Windows Explorer view. Even when I select the file, there is no preview
in the detail bar at the bottom. I only get previews for .mov and .mp4, but I no longer get them for .flv, .avi, or .wmv.
