Has your child ever been awakened with the loud "Ta-Daaam!" sound your laptop played when you opened it at late evening? Have you ever opened notebook on public meeting and the computer loudly notified everybody about your new messages or something? I bet you wanted to smash the computer into smithereens then! Each time this happens to me, I promise myself to disable the sound before logging off, but I always forget about this in few minutes.
Software making a computer quiet when it's turning on
I've created a small Auto Mute utility to make a PC silent when it's turning on or waking up. Solution is as easy as a pie! The sound is automatically muted when the computer is turning off or is going to suspend mode. The next system start is absolutely silent even if you forgot to turn the sound off in previous session. After that you can enable sound effects manually, using a shortcut combination. Moreover, you may use this keyboard shortcut to quickly switch the sound on and off when working.
This is quite late (at my side of the world), I couldn't make up a story for this so I just copy everything from the source. Well, at least I make my own screenshot.
