Windows XP x64 actually isnt true XP. Version 2002 and 2003 and XP x64 are not true Windows XP, rather they are forks of server 2003 that have XP'inizerd
btw i use arch, and you should too, shame on you. enable IPv6 or suffer from IPv4 deprectiation
who the fuck cares, yes its internally NT 5.2 which is 2003's kernel and its compatibility with xp software is piss poor, but it still says xp on the tin and doesn't have any of the server shit
