try this worked for me found this on other forums after windows 10 updated on me today and my triggers stopped working
Before, I could map combined accelerate & brake controls by pressing LT (recognized as Z-axis), now LT & RT work separately as Z-axis and Z-rotation. When I play, mapping seems inverted (e.g. accelerating if trigger is not pressed) and swapped (mapping LT to acceleration makes it brake and vice-versa). Really strange issue and I can't seem to be able to replace the generic "XINPUT compatible HID device" driver with anything more specific.
Edit/Solution? It appears like the old behaviour from before upgrading to Windows 10 can be restored by overriding the driver with the generic "HID compliant game controller" (sorry if I mistranslated that, my Win10 installation isn't set to English): While the controller is plugged in, open the device manager, open the properties of the "XINPUT compatible HID device", select to update the driver, choose manually and take the HID compliant game controller listed under compatible drivers. Note that I also (re-)installed drivers from http://support.xbox.com/en-US/xbox-one/ ... patibility
Solved the issue. Had to download the compatibility drivers that were for Windows 7 and Windows 8/8.1 and switch to them ("Microsoft XBox One Controller" instead of "XBox One Controller," and "HID-compliant input device" instead of "XINPUT compatible HID device").
EDIT: Just in case anyone else who has this issue doesn't know how to change the drivers:
Download the "PC drivers for Xbox One Controller" from here. (x64 if you have a 64-bit system, x86 if you have a 32-bit system)
Install them onto your system using the .msi you just downloaded.
Now, go into Control Panel>"Printers & Devices."
Right click the controller, go to "Properties," then hit the "Hardware" tab; you should see three items.
Click on "XBox One Controller," hit "Properties," hit "Change Settings," then go to the "Driver" tab.
Hit "Update Driver," then "Browse my computer for driver software," then "Let me pick from a list...," uncheck "Show compatible hardware," then select "Microsoft XBox One Controller." A warning will pop-up, but continue anyway.
Do the same and change "XINPUT compatible HID device" to "HID-compliant input device".
Restart, and it should work now.
