A driver is software that allows your computer to communicate with hardware devices. Without drivers, the devices you connect to your computer - for example, a mouse or external hard drive - won't work properly. Windows can automatically check if there are drivers available for new devices that you connect to your computer. For hardware that you've connected to your computer in the past, updated drivers might become available at a later date; but those drivers aren't installed automatically. To install these optional updates, go to Windows Update in Control Panel, check for updates, and then view and install driver updates that are available for your computer.
