You can upgrade any licensed and activated version of Windows 7 or 8.1 that's up to date on Windows Updates. If you have the Home version of 7 or 8.1, you'll get the Home version of 10. If you have the Pro version, you'll get the Pro version of 10. It will be licensed to your computer exclusively.
There is a media player included in Windows 10, but you can always add something like the VLC player if you wish.
Good luck.
