Flexible control of Win7 system microphone level

If we encounter the problem of the microphone when using the Internet audio and video communication, don't worry, the Win7 system provides a lot of user-friendly settings and details. Here, I share a setting skill for the Win7 system microphone enhancement function with my friends.
Right click on the volume control button at the far right of the Win7 taskbar and select “Recording device” from the pop-up menu.

Win7 system will directly open the "Record" tab of the sound control panel.
Here we choose the microphone device we are currently using, click the "Properties" button in the lower right corner.

In the "Microphone Properties" setting interface, we select the “Level” tab.
Here we can flexibly set the volume and intensity of the microphone.
