Microsoft has been powering a lot of different car entertainment systems over the years. Ford, Kia, BMW, Nissan, and Fiat have all used special versions of Windows to create their own interfaces and systems, but Microsoft is also focusing on its own "Metro" user interface for its Windows in the car future. At the company's Build developer conference this week, Microsoft's Steve Teixeira revealed what that future will look like. It's actually a lot like Apple's idea of CarPlay, a method to project what's on your phone screen directly onto a car's infotainment system display. Microsoft has created a concept that it's currently testing in real cars, and the idea allows Windows devices to mirror what's shown on screen into a touch- and car-friendly interface. The current prototype uses the connectivity standard Mirrorlink, an alternative to Apple's CarPlay system.
