Brumfondl: Question for Nathan at a guess: We have three machines here that have reserved our upgrades and one that is my Insider machine and already on build 10240 and set to send and receive builds and updates to my LAN. Does this mean that those three machines will get the upgrade much closer to or even the 29th since the build is in da house already?
The peer-to-peer download won't effect when the reservation upgrade kicks into place. On July 29 though you will be able to download the ISO and in place upgrade those other 3 downlevel Windows machines if you want
