Tomasc:
Thank you for your PM.
I can only relate my experience. I did it slightly differently from you: I launched Windows File Explorer, browsed to an .mpg file, right-clicked it, and selected "Open With" "Films & TV". That was when I got the notice to download the free mpeg codec.
I did not open "Films & TV" first.
This link might be helpful.
I don't think that there should be any difference between the Windows 10 Home and Pro versions with respect to this issue.
Sorry for the delay in responding. For some reason (old age?), I missed your response to this thread.
Have a great day.
Regards,
-Phil
