so how exactly do you start upgrade from inside windows from an iso? (serious question i really have no clue)grr. i assume you get an executable on the disk created. the only ISOs i have been dealing with over the past couple of years is the ubuntu one. so got confused.
Doing it now, installing the preview then will upgrade to the full version as I don't want to download the whole setup again I assume upgrade from preview to pro should be like the typical Windows Anytime Upgrade.
