Microphones don't work. None. What to do?

Question

Microphones

Win 10 pro x64. I tried a USB headset (microphone + headphones) from Logitech, I tried analog microphones (or what is the correct name for them?). Iron is guaranteed to work. There is sound in the headset, but the microphone is dead. On other computers, everything works perfectly - plug and play, everything is immediately picked up, no need to configure anything.
The point is clearly in Windows, since I recently changed my mother, and the problem is still there. Firewood is all downloaded from the motherboard manufacturer's website. All instructions from Google are fulfilled. What to do, I have no idea.

Answer 1

If the windows version is 1803, then go to “Settings” -> “Privacy” -> “Microphone” and activate the option “Allow applications to use the microphone“.

Answer 2

In the "Sound" settings, select the default recording device.
In the "Settings" application, find "Troubleshooting", there is "Sound Recording".
