ADVANTAGES AND DISADVANTAGES OF WINDOWS XP OS

Windows XP is a line of operating systems produced by Microsoft for use on personal computers, including home and business desktops, notebook computers, and media centers. The name "XP" is short for "experience".[3] Windows XP is the successor to both Windows 2000 Professional and Windows Me, and is the first consumer-oriented operating system produced by Microsoft to be built on the Windows NT kernel and architecture. Windows XP was first released on 25 October 2001, and over 400 million copies were in use in January 2006, according to an estimate in that month by an IDC analyst.[4] It is succeeded by Windows Vista, which was released to volume license customers on 8 November 2006, and worldwide to the general public on 30 January 2007. Direct OEM and retail sales of Windows XP ceased on 30 June 2008, although it is still possible to obtain Windows XP from System Builders[5] (smaller OEMs who sell assembled computers) until 31 July 2009 or by purchasing Windows Vista Ultimate or Business and then downgrading to Windows XP.[6][7]

The most common editions of the operating system are Windows XP Home Edition, which is targeted at home users, and Windows XP Professional, which offers additional features such as support for Windows Server domains and two physical processors, and is targeted at power users, business and enterprise clients. Windows XP Media Center Edition has additional multimedia features enhancing the ability to record and watch TV shows, view DVD movies, and listen to music. Windows XP Tablet PC Edition is designed to run ink-aware applications built using the Tablet PC platform. Two separate 64-bit versions of Windows XP were also released, Windows XP 64-bit Edition for IA-64 (Itanium) processors and Windows XP Professional x64 Edition for x86-64. There is also Windows XP Embedded, a componentized version of the Windows XP Professional, and editions for specific markets such as Windows XP Starter Edition.

Windows XP is known for its improved stability and efficiency over the 9x versions of Microsoft Windows.[8][9] It presents a significantly redesigned graphical user interface, a change Microsoft promoted as more user-friendly than previous versions of Windows. A new software management facility called Side-by-Side Assembly was introduced to avoid the "DLL hell" that plagued older consumer-oriented 9x versions of Windows.[10][11] It is also the first version of Windows to use product activation to combat illegal copying, a restriction that did not sit well with some users and privacy advocates. Windows XP has also been criticized by some users for security vulnerabilities, tight integration of applications such as Internet Explorer 6 and Windows Media Player, and for aspects of its default user interface. Later versions with Service Pack 2, and Internet Explorer 7 addressed some of these concerns.

The Windows eXPerience operating system is available as home and professional edition and are similar suitable for the use on standalone computers. The home edition is suitable for user which worked with Windows 9x/ME till now and don't need special network or security features in theire environment. If the user have used Windows NT/2000 private, in business or both, the Professional Edition is not only with a view of the administration optimally. Microsoft already encloses 10,000 drivers on the installation media of Windows XP, about the Windows update further more 2,000 drivers are available.

The Professional Edition of Windows XP has more network features than the Home Edition. An update of Windows 9 x/ME is possible, with Windows NT/2000 only the Professional Edition can be used for update. Optional FAT32 and NTFS are available as a file system for the installation partition.

Windows XP (Windows version 5.1) becomes a predecessor of Windows 9x/ME as well as Windows NT/2000 and is available for 32-bits CPUs in the following versions:

- Embedded
- Home Edition (1 CPU) for private user (Oct. 2001)
- Professional Edition (2 CPU) for business user (Oct. 2001)
- Media Center (1 CPU) especially for multimedia devices (Nov. 2002)
- Tablet PC Edition especially for Tablet PCs (Nov. 2002)
- Server Edition (4 CPU)
- Advanced Server (8 CPU), also 64-bit Intel CPUs
- Microsoft Windows Fundamentals for Legacy PCs (July 2007)

A 64-bit version of Windows XP was announced officially of Microsoft in April 2003. The RC2 was available in February 2005. Windows XP Professional x64 was published in April 2005. At most 16 gbyte RAM are utilizably with that, the virtual address range enlarges to 16 tbyte.

Same will be the product activation at all versions, which is needed at every new installation or extensive upgrade of the PC devices. Company customers can use an so-called Corporated version by a special licensing option without this product activation.

As the most visual innovation the revised Windows interface with the new design is well done, the design called Luna (as of beta 2428) can display window elements in high colour. The return to the interface as of Windows 2000 is further possible. The representation and organisation of the central registry is quit the same as used in Windows 2000.
