If you install all the included codecs/decoders you might get problem with other video software on your computer. Be careful when you install the software and disable addons that you don't want! Download = The software is bundled with advertising.See a video here showing the issue: Someone in another forum recommended installing VLC media player and associating all video files with it.This worked for some users who were experiencing this issue, but it didn't work for me unfortunately.
All older PDF files will still appear as a generic icon in the media library, and you will still have to use a PDF plugin to show a thumbnail preview on attachment pages.
I was using windows 8.1 -- which didn't have this problem -- when I upgraded to Windows 10.
I like everything about Windows 10 so far EXCEPT this.
And rebuilding the thumbnail cache didn't help either.
I went into a Best Buy and downloaded a few sample mpgs on a brand new Surface 3 running Windows 10 and the same issue -- preview pane video thumbnails do not update from video to video.
