I have a feeling that you can still turn off the Automatic Updates, if you so very desire. They just don't want the casual user being left vulnerable (i.e., they won't know to turn it off under My Computer-->Properties or to disable it in "Services"). After all, they are the ones who never use Windows Update and ignore the notifications in the Taskbar and are left vulnerable to all these internet worms. I've had the Automatic Updates turned off always, but I make sure to check the site. I prefer it that way.
