Configure touch pad by using Bootcamp control panel
I know this thread is out of date.
But for in case of other new mac user: you can configure your touch pad for click by touch in Bootcamp control panel. Just open your control panel, and look for Bootcamp item.
You can configure your mac keyboard, touchpad, ...
Ensure that you have installed bootcamp from your Mac OS installation disk to have the Bootcamp item available in control panel.
Mine is Macbook with windows 7 sp1.
I am using rEFI for multiboot on mac box.
