As  many of you may not have heard much about Windows XP Starter Edition because it was only preinstalled on PCs in emerging countries to offer a lower price point. The N editions (which do not include Windows Media Player) were sold only in Europe to satisfy antitrust requirements there. All Windows XP product versions, except Windows XP Professional x64 Edition, were available only in 32-bit versions.
