I thought that only pro version (except PC manufacturer) can be installed standalone, other edition has to have earlier version of window to upgrade. I remember that when I upgraded from 3.1 to 95 by tricking the computer to get a clean installation. I guess that I'm wrong.Quote from jperl:
Some confusion here. If you are building a new machine, you install the complete version of WinXP, not the upgrade. You only use the upgrade version of WinXp if you already are running a machine with win98 on it.
