Vostro 3650 Clean Windows 7 Install Complete - Touchpad Functions Gone

I clean installed windows 7 home premium x64 version 6.17601 SP1 on my Vostro 3650, resintalled all the drivers available on the site, but I'm not sure how to get back some touchpad functions. I used to be able to click both the left and right buttons to open new tabs/close new tabs in google chrome for example. I don't seem to have the option to edit touchpad settings and can't find any dell touchpad software.

I'm running the latest Bios (A17)
