"The big change is how IE now interacts with Windows Update: Before you had to opt-in to have "Recommended" updates installed automatically. It's likely few folks did. Now, IE upgrades are shipping as "Important" and this class of updates are defaulted to install automatically. A user can still opt-out and immediately after the announcement of this feature they also published details on how enterprises can opt-out. But still, this is a good move, it helps."
