About this interactive
A driver is a separate set of instructions that tells the operating system how to work with one device. There are far too many makers and models to build every driver into the operating system, so it carries default drivers instead: enough to get a device going the moment the computer starts, so you have a screen, a keyboard and a mouse before you have installed anything.
Often that is all a device needs. A flash drive, a plain keyboard, a monitor showing a sharp picture: if a device does everything you need, the default driver is doing its job, and there is nothing for another driver to add.
A default driver only covers the basics, though. When the screen is stuck at a low resolution, when Device Manager calls the graphics card Microsoft Basic Display Adapter, when a device's own extra features do nothing, or when the maker releases a driver with a new feature or a fix, install the manufacturer's driver. The lesson shows the ways in: in Device Manager, Update driver and then Search automatically, or Browse my computer for a driver you downloaded; double-click the maker's installer; or let a PC maker's tool, like Dell's, find the updates for you. The Driver tab in a device's Properties shows who provided the driver it is using and when.
The question for every card: is the device missing something it should be able to do?
