Hello everyone,
If you are having issues with your Xbox One controller, please be advised that the windows 10 anniversary update seems to have introduced issues with the Xbox One controller drivers.
The following is from an arstechnica article.
On Tuesday, a Microsoft representative confirmed that the Xbox engineering team was working on issues with controllers' "exclusive" modes, controller connectivity with certain games, and Steam Big Picture mode seeing two controllers where there should be only one. No timeline was given for fixes on those issues.
