Windows 10 K&N Edition Anniversary Update – Media Player Not Working

I own a Windows 10 K or N Edition which doesn't include the media player package. My problem is: I want to have preview thumbnails in the explorer for my MP3s and videos.

I had the issue before when I updated to Win10 but there this update saved me. Since the Anniversary update they are gone again.

Now I can install the old update but I still don't get the media player nor the preview images.

I tried most of the things Microsoft offers me but they are either not installable or don't work.

Any ideas what might be the correct update package?

Thx!
