Microsoft Windows XP Professional is the most famous OS developed by Microsoft. It is considered as the most complete yet ...



Development of Windows XP began in the late 1990s as "Neptune", an operating system built on the Windows NT kernel which was intended specifically for mainstream consumer use—an updated version of Windows 2000 was also originally planned for the business market. However, in January 2000, both projects were shelved in favor of a single OS codenamed "Whistler", which would serve as a single OS platform for both consumer and business markets. Windows XP was a major advance from the MS-DOS based versions of Windows in security, stability and efficiency due to its use of Windows NT underpinnings. It introduced a significantly redesigned graphical user interface and was the first version of Windows to use product activation in an effort to reduce its copyright infringement.

Upon its release Windows XP received generally positive reviews, with critics noting increased performance (especially in comparison to Windows ME), a more intuitive user interface, improved hardware support, and its expanded multimedia capabilities.Despite some initial concerns over the new licensing model and product activation system, Windows XP eventually proved to be popular and widely used. It is estimated that at least 400 million copies of Windows XP were sold globally within its first five years of availability,and at least one billion copies were sold by April 2014.
Windows XP remained popular even after the release of newer versions, particularly due to the poorly received release of its successor Windows Vista. Vista's 2009 successor, Windows 7, only overtook XP in total market share at the end of 2011.
Sales of Windows XP licenses to original equipment manufacturers (OEMs) ceased on June 30, 2008, but continued for netbooks until October 2010. Extended support for Windows XP ended on April 8, 2014, after which the operating system ceased receiving further support or security updates to most users. As of September 2015, Windows XP market share is 12.21% (and higher market share in China, at 30%,India; Asia in general and Africa), making it the second most popular version of Windows after Windows 7 (other statistics rank it third after Windows 8.1).
