How to test your joysticks and buttons
Open Devices & Printers. This is most easily done by pressing the windows key on your keyboard and then type "control panel". From there, click on "Devices & Printers".
Right click on an Xbox controller and select "Game controller settings"
Press buttons on your control panel and move the joystick around to verify all are working. This test will only work for ONE side of your control panel (see Step 5 for the other side). Note that pressing the 'home' button will close this properties box.
Close the properties box and then select the other controller in the list (Step 3) and then perform Step 4 for the other side of your control panel.
