The Xbox 360 Controller for Windows needs wireless receiver and wireless controller. If you don’t have wireless controller, then I suggest you to buy from the below site:

Amazon.com: Microsoft Xbox 360 Wireless Controller for Windows: Pc: Video Games

If you have the controller means just buy the receiver. I suggest the below site to purchase:

Amazon.com: Xbox 360 Wireless Gaming Receiver for Windows: Pc: Video Games

The Xbox 360 controller comes with 2x AA batteries. You can also buy a rechargeable battery which comes with a USB cable to charge it. The USB cable should be plugged to your system or Xbox 360.

I came to know there are two versions of wireless controller. One is for Windows and another one is for Xbox. But, the cost for Windows is more compared to Xbox.

So, I want to know:

1) Whether I require a wireless controller and recharger?
2) Why there is more cost for Windows?

The USB cable should be plugged to your system or Xbox 360.
