Unidentified devices appear unknown in the Device Manager with a yellow mark of exclamation, because Windows cannot recognize the hardware and provide drivers for them. Once the correct driver is installed, the hardware will start working and will no longer be considered “unknown.” Windows does a good job of identifying and automatically installing drivers for most of the common hardware available in the computer market, but there are devices which are not common or new enough yet to be added to the Windows driver database. In this article, we will discuss various methods of identifying and installing unknown device drivers. Before we begin downloading and installing the right driver for an unknown device, we must have its associated hardware ID. Note: Check if your Windows is updated by navigating to Settings app » Windows Update because drivers are automatically installed through Windows Update. If all pending updates are installed and the hardware is still not functional, proceed with performing the tasks below.
How to Find Hardware ID from Device Manager
If your hardware is not very common and you are not able to identify the device type for which you have to get the driver, this method will work for you. Windows can display Hardware IDs for all the detected devices in the Device Manager, whether their driver is installed or not. To manually identify an unknown device, you must follow the steps below:
Install Driver for Unknown Device
If the downloaded driver is an executable or MSI, simply running the executable will install the driver automatically. If you only downloaded the INF files, you will need to install the device driver manually. To install the driver, follow the steps below:
Using Software to Identify Unknown Device Drivers
If you are not satisfied using the manual method, you may use different software to automatically identify unknown devices. Some software used to identify unknown devices are discussed below.
Unknown Device Identifier
The Unknown Device Identifier enables you to identify the yellow question mark labeled Unknown Devices in Device Manager. And reports you a detailed summary of the manufacturer name, OEM name, device type, device model and even the exact name of the unknown device. Basically, it does the same thing we did manually. It will identify the device manufacturer, device type, model, and sometimes the name of the device. You just have to right-click on the device and select the Find driver. The results will open in a browser window from which you can select and download the appropriate driver for your device. Download Unknown Device Identifier
UnknownDevices
UnknownDevices is a small utility that was written to provide computer technicians with a simple way to identify those “Unknown Device” devices that show up in Microsoft Windows after a fresh install. UnknownDevices is a portable program that does the same thing as the Unknown Device Identifier. Download UnknownDevices
DriverIdentifier
DriverIdentifier scans your hardware with unique technology. This indicates the name of the manufacturer and the version of your device. DriverIdentifier has a huge database of drivers from all hardware manufacturers. This will give you the most updated drivers for your machine. The basic concept of DriverIdentifier is the same as discussed above. It will not download the drivers for you, but will guide you to the driver download sites using Google Search.

Automatically downloading and installing essential system drivers
After a Windows fresh install, the most important thing is the installation of essential device drivers so that your computer becomes usable. If you are sick and tired of identifying unknown devices in your device manager, and then finding and downloading the drivers separately, you will need an automatic device driver updater program. I will not go through the details of the driver updater as we have already discussed them in detail in another article. Just a quick summary here:
