Correct the whistling sound coming from a mic?

That whistling sound is called an Audio feedback and caused because of an endless loop caused when the mic picks up the sound of the loudspeakers and sends it back to the loudspeakers to amplify and picks up again
Ways to correct /avoid feedback

Face the speakers away from the mic or place farther away.
Lower their volume or mic gain

Use unidirectional cardioid mics which have a rear rejection that means no pickup from back side. Then you can use stage monitors facing you in the middle of the stage. And mic won't pickup them.

Ring out the speaker - deliberately create feedback by taking the mic closer to the speaker. When feedback happens, check the frequency on a real-time analyser and cut it using channel eq or graphic eq.
Use a feedback reducer

Microphone is not recognized on the PC?

Shut down and restart the computer and leave it for 20 minutes before connecting again
Update the driver in the device manager, uninstall the driver and re-insert the microphone
Use on another computer to see if it can be loaded, loaded out again after inserting the computer that can not be identified
Use the driver master, the brand comes with the software or the brand's official website to update the driver (such as Lenovo, Dell) to avoid the impact of missing drivers
