I needed to disable automatic updates in two places. In the Security Center and in the Automatic Updates, both of which are found in the Control Panel. Automatic Updates is still enabled in Services because I think that if I turn it off, it stops me from manually updating when I want to do it. But at Windows Update there is a button to turn it back on. Which I don't do.
Also in Internet Explorer, Properties, Advanced
Automatically check for Internet Explorer Updates
and both "Enable Install on demand...." options
(Although I don't know if any of that has anything to do with Windows Update at Microsoft)
I don't know if that'll help. Maybe something on your school network won't let you disable it.
