How to remap all controller buttons

Get an xbox one controller.

Download xbox accessories app from the windows store

After in game and in the controller layout screen under options simply create a profile in the xbox accessories app and swap till your hearts content. You need the game open so you can see what actions you are changing. I couldn't stand my sprint being on X and not being able to change it to L3. Keep in mind this only works with an xbox one controller and the elite controllers should already have software to do exactly that. Hope this helps anyone who wants to customize the controller. Just dont forget to change profiles back to default when you are done playing Halo MCC.
