How do I enable these features? I am running Win 7 64 bit on HP G72-262NR laptop. I have already updated drivers but no change .

These are referring to multi-touch enabled pads, which yours may not be.

It is a synaptics luxpad v7.4. I believe it is multifunction touchpad

Go to the Symantics site. MS has asked their PC OEMs to not enable these features for fear of an Apple lawsuit.
