I was smiling ear to ear when I read this. Microsoft is going to follow the trend set by Chrome and recently Firefox with doing automatic upgrades for IE.
It wasn't obvious from the article whether the automatic updates require the user to have opted-in to automatic updates via Windows Update or not. If that is the case these updates will be less widespread. [Update] Users do need to opt-in.
Another point to note is that Microsoft is still providing tools and options to prevent this automatic updating of IE aimed at businesses who insist of doing their own browser upgrade roll outs. This will continue to hamper IE upgrades in the enterprise space.
But at least this is a step in the right direction.
