Wait, hang on. You're right about Group Policy, but didn't the home version of Vista come with some kind of parental control feature that allowed you to restrict when the kid was able to do certain things, like they're not allowed to play games when they're supposed to be doing their homework, or they're only allowed to play games for a limited number of hours each day?

Or am I remembering that wrong? Or is that feature in SP1 (which is only at the RC stage at the moment)?

Anyway, I wonder if there's an extension to that feature that includes printer control.
