It is easy to check if your webcam is working. First, click on the “Start” icon and select “Camera” from the menu. Your computer will prompt you to allow access to the camera. If your webcam is functional, a window will pop up instantly, showing whatever is in front of your webcam (likely you if you’re sitting in front of it!). There are also some online third-party apps that you can use to run an online webcam test.
