The Microsoft Kinect for Windows SDK provides the native and managed APIs and the tools you need to develop Kinect for Windows Applications. Developers can create rich experiences by using Microsoft Kinect for Windows sensor technology on computers running Windows 7, Windows 8 developer preview (desktop apps only), and Windows Embedded-based devices. Developing Kinect for Windows Applications is essentially the same as developing other Windows applications, except that this SDK provides support for the features of the Microsoft Kinect for Windows sensor (color images, depth images, audio, skeletal data, etc.).  Click here to get more information and download the free software development kit.
