I have a 3 year old MacBook Pro, so I decided to experiment with Bootcamp. I changed it completly to Windows. Happily it worked, however there doesn't seem to be a way to mute the startup sound. I've searched the internet for answers but the problem is, but all the advice I find tells me either to mute the computer before turning it off (which unfortunately doesn't work), plugging in headphones (also didn't work), or downloading a mac application which I obviously can't as I'm in windows. Any help would be greatly appreciated.
