BIE just released Microsoft Windows XP Professional SP3 Integrated December 2010 Corporate. Thanks BiA for this, many of us are still on XP. No Serial Keys are needed.
With Windows XP Professional Edition with Service Pack 3, you get safer browsing and communication, powerful security tools, and improved experiences. Windows XP is the operating system release that unifies the Microsoft range, with all the desktop versions now built on the NT/2000 code base rather than the shakier foundation of Windows 95, 98, and Me. That makes XP a great upgrade for users of the now-obsolete 9x and Me line, but for those already on Windows 2000 Professional it is a closer call. Despite the similar name, there is no special synergy between Windows XP and Office XP, which works fine on Windows 2000.
