I like to control my mouse cursor with an Xbox 360 controller and joytokey. I've been doing it since Windows 7. However, ever since I have upgraded to Windows 10, the joysticks and buttons on the Xbox 360 controller now control the Win 10 UI without any 3rd part software whatsoever. For example, when I open the start menu I can navigate around with the left joystick and press A on the controller to open an app. The same sort of behavior occurs throughout the Windows UI.
I want to turn this off and use the controller exclusively through joytokey. Most people assume it is a setting in Steam. I don't have Steam installed on this PC and I have never had Steam installed on this PC. It seems to be a native Win 10 setting.
Can somebody help me figure out how to disable it? A setting or a registry value or anything.
I found a similar question on answers.microsoft.com (the most helpful site on the internet) which received no answer. There's also a question here on SU where the solutions are all Steam oriented and the controller is an Xbox One controller.
Edit: Corrected question that it is a Xbox 360 controller, not an Xbox One controller.
