11: A machine set up and autoimaged in a student computer lab. This way, a power cycle ensures that private data is not recoverable from the previous student.
Having been the admin at a school for a few years I can tell you that this already happens. Most schools now, well at least in Australia use a program called HDGuard where the image is reset back to a specified image every time the machine restarts. Its a great system but also very frustrating when you forget to turn it off before making changes to the image. Also if the systems are configured correctly they will have their personal information follow them on their personal network drive. That way things are set up the way that they like them where ever they go on campus.
