These drivers add support for the new Windows 8 gestures to your laptops touchpad (as long as it is made by Alps or Synaptics).
Download: Alps / Synaptics (Mirror)
Synaptics download is broken at the moment, must be popular :)
Works great on my old POS laptop, multitouch and everything, It never used to be able to do that. Who knew.
That's good to hear. I'll have to try some of our school laptops now. :D
