On Windows 7, Xbox One controllers are a bit hit and miss. It’s extremely likely that you will plug in your controller and get no response. There is a consistent solution on this reddit page, but that page is the only location on the entire internet where a proper fix is provided. In the case that this page disappears for any reason, I want to duplicate the solution here.
The problem: Xbox One controllers need some drivers to run natively, and these are usually not installed on PCs prior to getting the controller itself. The drivers are distributed through windows update, so it’s likely that you don’t have them.
The fix: These are the two updates you need:
User-Mode Driver Framework version 1.11 Link: http://support.microsoft.com/kb/2685813
Kernel-Mode Driver Framework version 1.11 Link: http://support.microsoft.com/kb/2685811
In case these downloads ever go dark, I’m mirroring the files here:
Install one kmdf and one umdf; there are 64 bit and 32 bit versions.
