Windows XP


Introduction

Windows XP is an operating system for personal computers introduced by the Microsoft Corporation in 2001 as part of its family of operating systems named Windows NT. It was available to selected users on the 24th of August 2001 and it became generally available on the 25th of October 2001. The Windows XP project development began late in the 1990s as “NEPTUNE” and it was based on the Windows NT platform. Windows XP was originally meant for general consumers, while Windows 2000 was planned for the use of commercial outfits. In January 2000, it was decided to combine both projects under the code name ”Whistler” which was later named Windows XP; XP standing for “experience.’’ It was released in two versions, the “Home” version and the “Professional” version. Windows XP represented a major advancement on the former MS DOS version of windows in several important technical features such as in data security, stability and efficient performance. Windows XP proved to be an instant commercial success and within the first five years of its release, it had sold over 400 million copies and by the 4th month of 2014, it had sold more than a billion copies. Much of this success is down to some specific advances which this version of Windows had over earlier versions for instance in terms of hardware support, a user interface that reflected deeper consideration for both usual and special needs of consumers as well as increased multimedia capabilities.
