Why do my Video Icons no longer show Thumbnail of video?

Hiya! Please help. Initially, my video icons in Explorer would appear as thumbnails of the video they represented. What I mean is, "La La Land.mp4", for example, would show as a rectangular snapshot of the video. But now, all my video icons are this standard default as seen here in this snap:


It's not a biggie. Videos play, but I kinda liked the way they appeared before.

Does anyone know how to fix this?

Thank you.

*Note I used a 3rd party app, called "BoostSpeed" that has a Win 10 Tweaker option. When run, it 'streamlines' Win 10 to supposedly run faster by applying a number of settings.
I am probably wrong, but I think one of the changes made may have disabled the video icons displayed as a thumbnail in order for explorer windows to open faster? That's the best I can come up with.

What do you think?

Hi there

Thanks to both of you! I read and printed the Windows 10 Customization Tutorial, by Brink, and it helped a lot. I downloaded K-Lite as well. I kinda like what I read about BabelSoft Media Preview and I'm going to go with that. What I find amazing is that it even does thumbnails for video files not supported by explorer, like FLV! Wow! I truly had no idea before. You guys made my day.

I'm currently ripping my collection to mp4 with the hopes of one day making a server to my devices, like smartPhone and smartTV. Any further help would be greatly appreciated- I'm knew at this >_<
