Microsoft have updated the Kinect for Windows SDK. I am not sure of the changes in the this build it was refreshed on the 5th and once again is the non-commercial version. I am still waiting to see some really cool examples of what can be done with the SDK.
Download the SDK from Microsoft Download
Gives Kinect for Windows developers easy access to the capabilities offered by the Microsoft Kinect device. This SDK is designed for non-commercial purposes only; a commercial version will be available in early 2012.
It includes drivers, rich APIs for raw sensor streams and human motion tracking, installation documents, and resource materials. It provides Kinect capabilities to developers who build applications with C++, C#, or Visual Basic by using Microsoft Visual Studio 2010.
