How to Use the Windows Device Manager for Troubleshooting
 

The Windows Device Manager is an important troubleshooting tool. It displays all your installed hardware devices and allows you to view which ones have problems, manage their drivers, and even disable specific pieces of hardware.

You should only need to use the Device Manager when troubleshooting your computer’s hardware and managing its drivers, but it’s an important system tool that you should know how to use.
