Hello Curly,

When you right click on the graphics device, click uninstall then it should prompt you on whether or not you want to delete the driver for this device.

Are you using a dedicated graphics cards such as an Nvidia or AMD? or is it the integrated graphics card that came with the computer. If you can provide your make / model of your computer I can direct you to the latest version of the display driver and possibly see if there is a bug with the specified KB update.
