Can I uninstall touchpad driver permanently?

Question

Can I uninstall the ELAN input device driver permanently?
I tried the Uninstall Device button and put a check on Delete the driver software for this device, but it still reinstalls it after I reboot the computer.
Also want to know Can I remove the ThinkPad tab on Mouse Properties?
I want my trackpoint(on touchpad unit) working as Microsoft's default behavior.

Solution

I found the answer by myself.

1.download your touchpad driver on Lenovo page
2.Install it, and open the folder that it was installed
3.find un_inst file and excute it
4.reboot your computer

Touchpad driver will be replaced with Microsoft default one and ThinkPad tab should be gone.
