You don't get Drivers through Windows Update, unless they are Microsoft Products.
You should obtain your Driver Software from your Computer or Hardware Manufacturer, **not through Windows Update (except for Mictosoft Hardware Updates),**as Microsoft normally does nor have those latest Drivers available as Microsoft relies
on the 3rd Party Hardware Manufacturer to supply them.
Go to your Computer or Hardware Manufacture's website > Driver and Software Support Section > look up your Computer or Hardware Model number > then your Operating System > locate the correct Drivers > download and install them.
