STEELSERIES ENGINE
You can find all the latest driver/firmware updates on the official SteelSeries support page.
SteelSeries has been using a convenient unified firmware update package their products for quite sometime now. The update takes around one minute to finish.
Through the SteelSeries engine you can map the 11 adjustable buttons, set the two DPI presets, adjust the ExactLift sensitivity, toy around with the illumination effects (intensity/pulsation), create profiles (and if you want bind applications to each of them) and finally you can use the statistics tab which counts how many times you've used each of the buttons inside a certain amount of time.
