Hexus posted a story that Microsoft has publically released Windows 10 IoT Core for the Raspberry Pi 2 and the MinnowBoard Max

The new OS is a software thrust into Internet of Things (IoT) territory to help Microsoft accelerate its goal of having Windows 10 on a billion devices by 2017. Windows 10 IoT Core is a free download but you will need an accompanying development system with Windows 10, Visual Studio 2015 and tools to get up and running.

Windows 10 IoT Core is a light version of the OS which can even run on a device without a display. There is no Windowed interface or desktop for IoT device users, instead you use a Windows 10 PC with Visual Studio 2015 and tools to create a universal app which will function as the interface for your maker device.

Microsoft released the first beta of Windows 10 IoT Core at BUILD earlier in the year but with this official public release it has implemented important upgrades to the OS, most significantly Wi-Fi and Bluetooth communications. Other key improvements include; improved support for Python and Node.js, up to 10x GPIO performance improvement on the RasPi 2, support for ADC and PWM audio.
