To install a game controller, follow the instructions that came with the device. When you plug in a USB controller, Windows should install the necessary drivers automatically.
Controllers that use connections other than USB ports aren't supported in Windows 7.
If Windows doesn't automatically find the driver when you plug in your controller, you can check Windows Update for drivers. For more information see Automatically get recommended drivers and updates for your hardware.
