Not all touchpads support the scrolling feature. The Elan and Synaptics drivers will both work with Windows 7. You would need to install the driver that corresponds to the brand of touchpad that is used in the system. You can identify which hardware is in your computer by going to the Driver download page, and downloading the hardware detection utility. You would need to click on the link "Need to know the hardware on your system to choose the right drivers?"
