The quickset seems not work well with windows 8

Hi

On my v131, I newly installed windows 8, then I can't find the quickset for win8, so I installed quickset for win7. It partially works, because when I press the "wrench" button, it will trigger dell support center, but when I press the "gears" button, it won't trigger the quickset.exe but as the action as "winkey+x".

Does anyone know how to make it work again? 

Thanks.
