Ahhh  I see what youre 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  Thats what WPV would have us do    As for the clean install part well Vista only supported direct upgrades from XP not  so its not out of the realm of possibility that theyll only support directupgrading 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  reinstall the programs and restore their data For PCs running Windows Vista customers have the option of an inplace upgrade of Windows  keeping their data and programs intact or to perform a clean install of Windows   So thats that  If Microsoft announces something different in the future then we can amend the article
