Drivers are programs that hook directly into Windows and control the essential tasks of communicating your instructions to a hardware device and then relaying data back to you. Windows 10, like Windows 8/7, includes most, if not all of the device drivers for common hardware.  All you have to do is plug in the hardware and the drivers will install.

Microsoft Hardware Device Drivers for Windows

But if need to install or update any drivers for Microsoft Hardware products in your Windows computer, you can visit Microsoft Hardware Support for Windows. They include Drivers for Mouse, Keyboards, Desktop sets, Games, Headsets, Webcams and so on.

The webpage lists all available device drivers compliant with Windows for products by Microsoft Hardware divisions.

While Windows 10, Windows 8, Windows 7 and Vista offers the plug and play feature, you might want to backup some installed drivers, if you don’t have the Driver CD that came with the computer or they are unavailable online. This comes in quite handy if you purchase a computer and want to backup the initial set of drivers. It can be quite difficulty for example to find drivers for hardware installed in a notebook if the operating system has to be setup again.
