Eduardo posted a link above for the 10547 iso which works with no problems; it's the one I used. After upgrading to that iso, the 10565 should show up almost immediately if you have Fast selected...

Update: I downloaded the iso file for 10547 and updated Windows. It activated with no problem. I just finished updating again with build 10565. Worked flawlessly. Thank you Eduardo. Thank you...

I am in the US and I too am having no preview installs under update. I guess I will try the iso file.
