Microsoft has released PC drivers for the Xbox One controller. The controller will support all configurations which are designed for the Xbox 360 controller.
In order to use the controller on a PC, controller will now need to be connected via a micro USB for the function to be made available. You can find the appropitate 32 and 64 bit drivers via Major Nelsons blog.
There is no word as of yet if and when a wireless version of the controller will be usable on the PC.
