Am I understanding the article correctly that it's for new installs only?

Also is "on by default" the right wording for something that needs a registry change to turn off? That just seems like it's forced with a workaround that they'll remove at some point.

Last point, does that mean that windows is going to take a massive speed penalty going forward since they also default to their slow software encryption over hardware encryption?

Man this kinda blows. I'm hoping that W12 will have all this Vista-esk transition crap sorted out by the time it launches.
