If you never want beeps from the console, stop or disable the beep service.

For example,

net stop beep

in an Administrative command prompt.

What is this?

The BEL character/code: https://en.wikipedia.org/wiki/Bell_character

And how to off this behavior?

Don't send character 7 to the console when you don't want it to beep.
