Windows XP Software
Windows XP is a major revision of the Microsoft Windows operating system created for use on desktop and business computer systems. As of February 2006, it is the latest general-purpose version of Microsoft's family of operating systems, and is expected to be succeeded by Windows Vista sometime in the second half of 2006. Codenamed "Whistler" during its development, Windows XP was released on October 25, 2001. The letters "XP" are said to come from the word experience.
The most common editions of the operating system are Windows XP Home Edition, which is targeted at home users, and Windows XP Professional, which has additional features and is targeted at power users and business clients.
Windows XP is known for its improved stability and efficiency over previous consumer versions of Windows. It introduced more efficient software management to avoid the "DLL hell" that plagued older consumer versions of Windows. It presented a significantly redesigned graphical user interface (GUI), a change Microsoft promoted as more user-friendly than previous versions of Windows. Windows XP is also the first version of Windows to use product activation to combat software piracy, a restriction that did not sit well with some users and privacy advocates.
You can often find Windows XP software at a discount eBay. A software store may have gotten surplus copies of Windows XP software or wish to reduce their Windows XP inventory due to an updated version and will sell new copies of Windows XP at a reduced cost. Before you bid on an auction, make sure that the Windows XP product says the product is "new and in a retail box".
