Microsoft is launching a Preview Program for its Windows 10 Xbox app, similar to what it has on the Xbox One console. The Xbox Beta app will let fans "provide early input on features and enhancements coming to the Xbox app on Windows 10, helping us shape the product based on fan feedback," according to Xbox Wire. That's not as exciting as previewing early games, of course, but the Windows 10 Xbox One companion app has gradually become pretty handy, especially if you're into features like online gaming, achievements and console streaming.
