Awhile back I had problems with my movie program and after searching the net, it was recommended that I turn off the thumbnail preview of the videos (.avi, etc.). So in folders view, if I set it to thumbnail, there's no first-frame picture/image that shows up for the videos. My picture previews are still functional.
Now I want to turn the video preview back on, but I forgot how! Does anyone know how to?
I think (not sure) that I went to "RUN" command and typed "cmd" but I forgot what I did beyond that. Or it could be something else that only affected the video thumbnail preview.
