ahhh i see what you're getting at what we should probably do then is disclaim anything from the tech arp source with something to the effect of according to documents obtained and published by technology web site tech arp like i said there are a lot of tech news web sites that are repeating this and the quality of the information shown in the tech arp documents is pretty consistent with how microsoft goes about things so i believe it should stay in that's what wp v would have us do as for the clean install part well vista only supported direct upgrades from xp not so it's not out of the realm of possibility that they'll only support direct upgrading from vista the register contacted microsoft on the topic of xp upgrades and they responded with '' i can confirm that customers will be able to purchase upgrade media and an upgrade license to move from windows xp to windows however they will need to do a clean installation of windows this requires the user to back up their data install windows re install the programs and restore their data for pcs running windows vista customers have the option of an in place upgrade of windows keeping their data and programs intact or to perform a clean install of windows so that's that if microsoft announces something different in the future then we can amend the article talk
