Windows 10: Camera Hack?

My son recently joined an online school tutorial. To begin with, he was required to test his connection for the camera, audio, microphone. He is using the most updated OS, however the camera failed which subsequently stopped him from joining. When we contacted the company running the system their hack was to shine a light into the camera which fixed the problem. How is this so?

Thanks for updating us on the results of the troubleshooting steps that you have completed. Since the built-in webcam is still not working correctly and the same error code 0xA00F4244 (0xC00DABED) is still appearing, we suggest that we check the camera privacy
settings to see if the camera access is turned on. Kindly follow the steps below to check the camera privacy settings:

• Press the Windows key + I to open the Settings app.
• Near the top of the Settings app window is the search box, kindly type the word "webcam" or "camera".
• From the list of results choose Camera privacy settings.
• Make sure that "Let apps use my camera" toggle is set to On.

We look forward to your response once you complete the steps.
