I have a new computer with Sound Forge Pro 11 and Windows 10 with 64 gb of memory.

I have a small mp3 file I use to check speakers, players, etc.  I right click on the file and several players are listed:  Internet, Sound Forge, Windows Media Player, and I-Tunes.  I check Windows Media Player.   But it seems that at random intervals when I click on the file it loads Sound Forge.  If I close SF, go back to the mp3 file, check Windows Media Player, it still seems to default to Sound Forge.

Do I have something set wrong in Windows 10 or Sound Forge?  How do I fix it?
