Generally speaking, we don't record exams, but just in case, we can turn off the recording permission of exams, so that we can feel at ease. The method to turn off the recording authority on the computer side is as follows: 1. First, turn on the computer, click the Start button in the lower left corner of the screen, and select the "Settings" menu item in the pop-up menu. 2. Then, click the Privacy icon in the computer system settings window that opens. 3. At this time, you can open the privacy settings of the computer system. In this window, click the Microphone menu item in the sidebar on the left. 4. Then, find the setting item "Allow applications to use my microphone" in the window on the right. 5. Finally, set the switch under this setting to "OFF".
