It's been pointed out in the Win7 group that uninstalling
and hiding only works for the current version. Apparently
MS issued at least one "update" of that patch, with a
new video in it, which then overrode peoples' settings
because it was technically a new version of the patch!

So for anyone who leaves auto-update enabled there
may be no escaping. It might be like non-activation.
Instead of nagging you to say, "This Windows in not
genuine" it will nag you to say, ""This Windows is outdated".

That actually makes a lot of sense for MS. It would be a
way for MS to define Windows as subscription software
retroactively and make it very difficult for most people to
keep using Win7.... all in the name of customer service.
