Downloading the SDK and the Developer Toolkit
The Kinect SDK and the Developer Toolkit are available for free and can be downloaded from http://www.microsoft.com/en-us/kinectforwindows/.
The installer will automatically install the 64- or 32-bit version of SDK depending on your operating system. The Kinect for Windows Developer Toolkit is an additional installer that includes samples, tools, and other development extensions. The following diagram shows these components:
Note
The main reason behind keeping SDK and Developer Toolkit in two different installers is to update the Developer Toolkit independently from the SDK. This will help to keep the toolkit and samples updated and distributed to the community without changing or updating the actual SDK version. The version of Kinect for Windows SDK and that for the Kinect for Windows Developer Toolkit might not be the same.
