This week, the Lanner consulting team offers a quick tip to silence WITNESS sounds that you may not need.
When you click on Validate in an actions block or in a rule, then Windows will give a beep sound. If you are in a busy office this may be annoying to colleagues or indeed to yourself.
Muting and volume control have no effect on the beep; you will still hear the tone. To silence the tone, use the following commands:
From a command prompt (Start / run / CMD)
net stop beep
sc config beep start= disabled
Note in the final command that the spaces must be exactly as shown.
There are various technical sites for Microsoft users where these things can be researched in more detail, e.g.
