360 controller driver?

I may have downloaded the wrong driver(I think that's what it is called).is there any way to change or delete it?

If it's a USB controller.

Then try going to Control Panel, Device manager, Universal Serial Bus Controllers, then right clicking the Controllers name, and uninstalling it. Then restart, during boot up, plug the Controller back in, and if your using Vista/7 then it will find the hardware and use Windows update to install recommended drivers for it. If not then find the correct drivers if you believe you have made a mistake.

the driver is included in vista or 7....u just need the software
