Microsoft Windows XP Professional is the next-generation operating system for businesses of all sizes, and for individuals who demand the most from their computing experience. Windows XP delivers all the features you need for the digital age - including tools for creating and managing digital photos, music, and video, or for building a small network - all in one box. Windows XP is built on Windows 2000 to give it a solid, reliable foundation. It then builds on this foundation with new multimedia capabilities, Internet Explorer 6, new Internet security features, and much more. Plus, an improved, task-based visual design puts the features you use most often in the foreground.
Service Pack 2 (SP2) is all about security, and it’s one of the most important service packs ever released. It provides better protection against viruses, hackers, and worms, and includes Windows Firewall, Pop-up Blocker for Internet Explorer, and the new Windows Security Center.
