Windows 7 Home on notebook. I installed optional update for nVidia (Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3, Other hardware - NVIDIA GeForce 9300M GS). Although everything is working normally and I dont have errors, I noticed that this update mainly intended for improving gaming performance, and has installed a varios extra stuff, nVidia 3D Vision Driver, Graphic Driver 327.02, Update 1.14.17 As I don't use my laptop for gaming, I don't really need this update. How to unistall this update properly, all it components and registry entries? Also, I think driver update removed the previous drivers during the installation process.
