No.. I don't want to join!

So this is another annoying Microsoft thing with Vista - They ask you if you want to share usage information with Microsoft on your computer usage and other stuff. But the OK button is disabled.. So in order to say No, I have to first say Yes and then say No to enable the OK button... then you hit OK and have to elevate the decision to the system administrator to allow and confirm that you really didn't want to join.

I had to decline this "great offer" once when installing Vista, and now again after installing Service Pack 1. Not only is it hard to say "No" but you have to say it multiple times - awesome...
