OK everyone. Keep in mind all picture thumbnails work and its only video thumbnails that have problems. I did something that someone helpful suggested and I used another work laptop with Windows 10 to see if these MOV files thumbnails would work, and the MOV files thumbnails did work. So it's not the issue with the file itself. The MOV files are good. However, certain MPG/AVI thumbnails will not work with either laptops, so does that mean those particular files' thumbnail settings are corrupt?
So for the MOV files thumbnails that work on my Windows 10 (work laptop) BUT does not work with my new Windows 10 (home laptop), and I deleted my thumbnail cache, what can I do? It's a brand new computer but obviously something is happening that is causing the MOV thumbnails to not work. Is it a laptop brand thing? Work is Lenovo laptop and home is Asus laptop.
