Optiplex 9010 All-In-One Update Video Drivers

<#I initially wrote this script to update the drivers on Dell Optiplex 9010, 9020, & 9030 All-On-Ones, due to Adobe Illustrator CC 2015 GPU acceleration. I ended up only needing to run this on 9010s, so the model detection isn't necessary, but I left it in.

I had to remove the old driver due to Dell not having a newer driver on their site for the 9010. I fetched it from Intel since the GPU is the HD Graphics 4000.

#This script is to update the Intel HD Graphics from the Dell One's to the most recent intel Release on the 9010 All-In-Ones.
