They stop doing it when I tell them to knock it off, and they don't creep back in and do it again after a few months, either. The update responsible for the notification, even after I removed it and hid the update within WU, found its way back after MS released an 'update' to the package with the totally unintended, honest! side effect of unhiding the package and reinstalling it.

Oh, I wish what you said was true. It's funny because they didn't do that when I was on an older version of Ubuntu (11? 12? I forget). It just kept popping up and telling me to update no matter what I did. Stuff like this: http://askubuntu.com/q/218755
