This controller works perfectly with Windows 7 you do not need to install a cd you just plug it in your usb port and it installs the driver and your ready to go. It is like a PS2 controller if you like PS2 controllers I would recommend this product. Not only does this controller work on Windows it works with your Playstation 3 as well. Just plug it into your usb port on your PS3 and it works fine... The only thing if you use it on PS3 the buttons have numbers on, not Cross, Square, Triangle and Circle and also Back and Start. And has an ANALOG button. So don't get confused! Also a great price!
