Right-click the unknown device and select Properties to view more information. Although we may be able to see a name for the device, Windows doesn’t know what it is and we don’t know specifically which drivers we need for it. For our purposes, the difference doesn’t matter. Such devices will often have the name “Unknown device,” but they’ll sometimes have a more descriptive name. Each device with a problem has a little yellow exclamation mark over its icon. You’ll find unknown devices and other non-functioning devices under Other devices. The Device Manager can also be accessed from the Control Panel or with a search from your Start menu or Start screen. On Windows 7, press Windows Key + R, type devmgmt.msc into the Run dialog, and press Enter.

To open it on Windows 10, 8.1, or 8, right-click in the bottom-left corner of the screen or press Windows Key + X and select Device Manager. You’ll see information about Unknown Devices in the Device Manager. RELATED: How to Use the Windows Device Manager for Troubleshooting
