i thought the reason for the SHUTDOWN switch would be for when you want to kick off a defrag process and couldn't be bothered to hang around while it does its thing.
start it off & go to bed, safe in the knowledge it wil turn your PC off for you.
why would you want it to turn the PC back on?
on a server maybe, i could see the point. or any similar PC that you want 24/7 access too.
