Is there an adapter to connect XBOX 360 controller to the PC

You could just buy a gamepad for the PC.

If you want a wired controller it's simply a matter of downloading the drivers from microsoft. (Available here: Microsoft: Download Gaming Software) For a wireless controller though, you have to buy a usb receiver like this: Microsoft Xbox 360 receiver

actually in windows vista, the xbox 360 controller is automatically recognized!!! just plug it in

Interesting, I didnt know you could do that.

yeah, just buy a wired X360 controller, plug it in, and XP (and Vista too, i'd assume) will automatically DL and install the necessary drivers. then its just up to you to configure it in the game controllers section of the control panel.

but if it is a wireless one you got to buy an adapter for 16.99. make sure your xbox 360 is not nearby or it will turn on

Will the wired 360 controller work with windows 7 OS? Also where can you buy the adapter?

it will work and i recommend using the wire

Here is a controller that comes with the wireless reciever

Yep fairly common and you can use multiple controllers on 1 adaptor I did it this way 'cos my son already had 3 xbox controllers and therefore it was cheaper than buying a new pc game pad. I got one for about £10 2nd hand on ebay about 6 months ago. Bosh £10 3 decent gamepads for my PC.

Do not know where you are in the world but here is a link for a simple search on PC, xbox, wireless receiver done on ebay.co.uk

You can also use a ps3 controller if you preffer, It takes a few mins to setup once you have foudn the drivers, but then it works flawlessley, great one my PSX emulator
