A webcam not working in Windows 11 can be related to a built-in camera or an external camera. How do you know if the camera is not being detected? Simple: the screen may be black, the camera light may be off, or nothing happens when you try to access the webcam.
Windows 11 – How to Fix Webcam Not Working Issue
There are two possible reasons: hardware or software. Unlike something that doesn’t work properly in Windows, a webcam is a physical device, so the problem could be with the device itself or with your computer’s understanding of how to connect to it.
Most Windows webcam issues have something to do with software. That is, either Windows 11 doesn’t understand that the camera is connected, or the software you’re using (such as a browser or video program) doesn’t have the correct permissions enabled, effectively blocking access to the camera.
If you've already connected and set up your webcam with Windows, but your computer isn't detecting it, try these troubleshooting steps to determine where the error is and what to do about it. Test your webcam after each step to see if it's resolved before moving on to the next tip.
