Extract the zip file you downloaded to a folder. then go to Start > Control Panel > Device Manager and locate your unrecognized hardware probably under "other devices" or "network adapters" with a yellow exclamation mark . . . right click on it select "update driver software" > "Browse my computer for driver software" then enter the path of the folder you just created and select next . . . if you choose the right hardware and driver windows will install the driver otherwise it will give you a message that the driver is not compatible with the hardware you selected.
