Installing the drivers is pretty easy. Major Nelson’s post dropped thesee quick link to the drivers.
If you’re not sure whether your version of Windows is 32 or 64-bit, you can bring up the System panel by hitting Windows Key + Pause or going to your Start Menu and searching for System. It’ll indicate under System Type what you have.
Download the appropriate driver, but be aware that this is a new file that hasn’t been verified yet, so your browser might call it suspicious.
Once you download the file, installation is as simple as agreeing to the license agreement that you definitely read all of and clicking Next a few times. You’ll have to restart your PC for the drivers to take effect. Once you reboot, though, you’ll able to plug a Micro USB cable into your Xbox One controller and then to your PC. The controller will buzz and then light up to indicate the connection is good.
Keep in mind that the Xbox One controller doesn’t yet have any wireless functionality for PC gaming. If it proves a popular peripheral as the Xbox 360 controller has, there’s a good chance Microsoft will release a device to allow such a connection, but there isn’t anything available right now.
With that said, you can now use your Xbox One controller as a PC gaming device without having to resync it each time you want to jump platforms. The controller works well and just as seamlessly as its predecessor. I still didn’t beat my Pac-Man CE DX high score, however, so it doesn’t have any magic powers.
