Things You'll Need
Instructions
Kinect for Windows SDK (beta)
Hook up your Kinect to your Windows 7 PC via USB port, just as you would when connecting it to the Xbox 360's USB port (you may be more familiar with this as the port that charges controllers).
Download the official software from the Microsoft website. It installs easily in just a few minutes.
Explore the SDK tools. This software gives you access to raw data directly from the Kinect sensor streams, and skeletal tracking ability.
OpenKinect
Download the OpenKinect drivers and extract them from their compressed (.zip/.rar) file to a new folder on your hard drive.
Connect the sensor via USB, then launch Device Manager from your Windows Start Menu. Windows will attempt, and fail, to auto-detect the Kinect.
Under "Other Devices" in Device Manager, find "Xbox NUI Motor" and right click. You will be given the option to update the driver for the device. This is where the OpenKinect drivers come in to play. Select "Browse My Computer for driver software," then press the "Browse..." button to select the folder with the OpenKinect drivers from Step 1.
Return to Device Manager, where you should see the updated drivers. Select them for installation.
Return to the folder containing the extracted OpenKinect files. Select the folder inside for Kinect Demos, then select KinectDemo.exe. You should now have access to live data from the Kinect sensor streams.
