How to Check Registry Errors in Windows 10

On Windows 10, every device (keyboard, mouse, motherboard, processor, memory, etc.) connected to your computer generates a status code in Device Manager, which reports whether the hardware is operational or if it has issues.

If you're noticing problems with a specific piece of hardware or a device shows a yellow exclamation, red "X," or down arrow mark, understanding its operational status should be one of the first steps to diagnose and try to fix the issue.

In this Windows 10 guide, we'll walk you through the steps to determine the status of the hardware installed on your computer as well as the steps to troubleshoot and resolve common problems.

Once you complete the steps, if the status reads "This device is working properly," then the hardware is not experiencing issues connecting to Windows 10.

If the component isn't working correctly, then you'll see a description of the problem with an error code. For example, if you see "error code 22," then it means that the device has been disabled, and you must enable it to address the problem.

How to fix hardware status problems on Windows 10

The status of a piece of hardware connected to your computer can show many status codes available, and depending on the message, the solution may have different steps.

Below you'll find a list with the most common error codes and recommendations to resolve them.

Fixing Device Manager error codes reinstalling driver

The following list includes the error codes along with their respective description that you can resolve by updating the driver package:
