Microsoft has quietly previewed their "Windows in the Car" infotainment system at the Build Developer Conference.

Described as a "connected car concept," Windows in the Car has a Start page with several preset areas where commonly used functions can be "pinned" for easy access. The system appears to operate like a tablet and users can swipe side to side to access different screens such as "My Drive" and "My Apps."

Speaking of the latter, we can see familiar apps such as Pandora, Spotify and TuneIn Radio. The screen also shows the Trapster app which displays the location of red light cameras, speed cameras and speed traps.

While Microsoft didn't get into details, the system has attractive interface with a sleek telephone / contact display. The system can also read text messages aloud but, unfortunately, the map display is "really small."

Microsoft is currently testing the system in simulators and prototypes but it's still a concept.  Regardless, they're working on it "very, very seriously."
