I have noticed that sometimes a command window can generate a beep, even if the sounds is turned off. Can I stop this ?

This is rather embarrassing in a library where you are meant to have the computer on silent.

Thank you for this, chaps. I make many many mistakes and the noise was driving me round the beeping bend. – Brian Hooper Mar 3 '11 at 8:54

To silence the current session:

net stop beep 

To silence for good:

sc config beep start= disabled
