This is out now, available for manual download in the bowels of the microsoft site. won't be coming out through auto update for a while, though.

Remember:
Turn off all virus scanners/firewalls prior to install
Make sure nothing else is running
It takes a while, so go get a drink or something while it runs.


Should get you an extra 10% performance, allegedly.

Odd, I found the official link, but it leads me to a 404 page.

So, two questions:

Could you provide a link that worked for you? And, is it really worth it? I don't want to spend all day downloading something that hardly makes a difference.

Direct file link.

And yes, i've noticed the performance boost. Makes things a bit quicker on startup.
