You should obtain your Driver Software from your Computer or Hardware Manufacturer, not through Windows Update (except for Microsoft Hardware Updates), as Microsoft normally does not 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.
