It should be called rear steering in the Vehicle Specific column and G & H Functions in the Vehicle column.
Wrong. Most computers aren't made with built in Bluetooth. If it's an Xbox Controller wit Bluetooth capabilities, you're going to need the wireless USB adapter made by Microsoft that hooks up to your PC.
You could also use a most recent Win10 update that has Bluetooth compatibility with Xbox controllers. It's what I did before resorting to MicroUSB > USB, Bluetooth can be random for me.
That's odd. It's idk, the Win10 Anniversary Update or something. All I know is that if it's updated, you should have it. Either way, as long as the controller works.
