Controls for touchpad on E1505 Laptop with Win 7

After a nightmare upgrading my E1505 Laptop to Win 7, I don't have the touchpad options anymore.  How can I turn off the touchpad's features?  I tried to find the drivers on Dell, but Windows 7 on my Laptop are not an option.

Windows was installed as a clean install (eventually).  The touchad works as well as an external mouse.
