Windows comes with drivers for many devices, such as printers, displays, keyboards, and TVs. A driver is software that a device uses to work with your PC. Every device needs a driver to work with your PC. So, in many cases, you can plug in a device, and it’ll work automatically.
Windows can also download device software and info. This might include an app that the device manufacturer created to go with your device or info like the product name, manufacturer, and model number, to help you distinguish between similar devices.
Drivers are updated occasionally. Windows can update them automatically, or you can install the updated drivers yourself. It's important for you to have confidence in the updated drivers you install. Windows notifies you if it detects a suspicious or unsafe driver you shouldn't install.
Windows Update checks for updated drivers and software for your devices and install them automatically. Keeping Windows Update on is a good way to make sure your devices continues to work properly and you get the best experience with them.
PCs running Windows RT 8.1 always automatically download and install drivers, apps, and info for your devices.
