My microphone is not working on Windows 10

My microphone is not working on Windows 10

When the microphone does not respond on Windows 10, you should check for settings or connection issues instead of hardware failures. First check whether the microphone is disabled or muted: click the taskbar sound icon to enter "Sound Settings" to see if the microphone is selected in the "Input" section and the volume bar responds; if there is no response, enter "Device Properties" to confirm that it is not muted, and check the microphone permissions in specific applications (such as Zoom or Teams). Secondly, make sure that the microphone is correctly identified: plug and unplug the device and replace the USB interface; check whether the device exists through the "Record" tab of the "Sound Control Panel", and enable it after disabling the device; update the sound card driver if necessary. Then check the privacy settings and permissions: go to "Settings" → "Privacy" → "Microphone" to ensure the global

How to reset network settings in Windows 11

How to reset network settings in Windows 11

Resetting network settings can solve Windows 11's Wi-Fi connection, slow network speed and DNS abnormalities, and do not delete personal files. The specific steps are: Press Win I to open the settings, click "System" → "Troubleshooting" → "Network Reset", or search for "Network Reset" directly; this operation will restore the network configuration to the initial state, including deleting the saved Wi-Fi password, resetting TCP/IP and DNS, reinstalling the driver and clearing the virtual adapter; select "Reset now" or "Scheduled Reset" when executing, and the system will automatically complete the process after confirmation; precautions include backing up the Wi-Fi password in advance, ensuring the power is stable, and clarifying that it cannot solve the problems caused by the router or ISP.
