Ah cool. Microsoft has provided the 32-bit and 64-bit (x86) drivers for their Xbox One controllers. The controller can only be used in wired mode, connected to the PC with a micro-USB cable, and there does not seem to be any plans to develop a PC wireless dongle like the 360 had. It will support any game which can make use of an Xbox 360 controller, which is certainly a lot of games.
The D-Pad is said to be a huge step up from the 360, which is a polite way of saying the 360's directional pad was absolute garbage. I am hesitant about the rest of the controller, though. I have heard numerous complaints about its design, particularly with its shoulder buttons, although it is hard to know without physically trying it. Like all peripherals, I would expect it comes down to personal preference to some extent.
PC gamers have other choices, too. For instance, unofficial support for the PS4 controller exists, albeit it is missing features from what I remember (it does support Bluetooth wireless on the PC, however). Also, and this is a better option, numerous PC gaming companies have their own controllers, including Razer, Logitech, and others.
But, of course, if you already have an Xbox One — then why not try its controller on your PC?
