Define Windows XP (eXPerience)?
Windows XP is an operating system produced by Microsoft for use on personal computers, including home and business desktops, laptops and media centers. First released to computer manufacturers on August 24, 2001, it is the second most popular version of Windows, based on installed user base. The name "XP" is short for "eXPerience", highlighting the enhanced user experience.
Windows XP, the successor to Windows 2000 and Windows ME, was the first consumer-oriented operating system produced by Microsoft to be built on the Windows NT kernel. Windows XP was released worldwide for retail sale on October 25, 2001, and over 400 million copies were in use in January 2006. It was succeeded by Windows Vista in January 2007. Direct OEM and retail sales of Windows XP ceased on June 30, 2008. Microsoft continued to sell Windows XP through their System Builders (smaller OEMs who sell assembled computers) program until January 31, 2009. On April 10, 2012, Microsoft reaffirmed that extended support for Windows XP and Office 2003 would end on April 8, 2014 and suggested that administrators begin preparing to migrate to a newer OS.
The NT-based versions of Windows, which are programmed in C, C++, and assembly, are known for their improved stability and efficiency over the 9x versions of Microsoft Windows. Windows XP presented a significantly redesigned graphical user interface, a change Microsoft promoted as more user-friendly than previous versions of Windows. In an attempt to further ameliorate the "DLL hell" that plagued the past versions of Windows, improved side-by-side assembly technology in Windows XP allows side-by-side installation, registration and servicing of multiple versions of globally shared software components in full isolation. It is also the first version of Windows to use product activation to combat illegal copying.
During Windows XP's development, the project was codenamed "Whistler", after Whistler, British Columbia, as many Microsoft employees skied at the Whistler-Blackcomb ski resort.
According to web analytics data generated by Net Applications, Windows XP was the most widely used operating system until August 2012, when Windows 7 overtook it. As of December 2013, Windows XP market share is at 28.98%, having decreased almost every month since at least November 2007, the first month for which statistics are publicly available from Net Applications.
New and updated features
User interface
Windows XP featured a new task-based GUI (Graphical user interface). The Start menu and taskbar were updated and many visual effects were added, including:
A translucent blue selection rectangle in Windows Explorer
Drop shadows for icon labels on the desktop
Task-based sidebars in Explorer windows ("common tasks")
The ability to group the taskbar buttons of the windows of one application into one button, with a popup menu listing the window titles
The ability to lock the taskbar to prevent accidental changes (Windows 2000 with Internet Explorer 6 installed had the ability to lock Windows Explorer and Internet Explorer toolbars, but not the taskbar)
The highlighting of recently added programs on the Start menu
Shadows under menus (Windows 2000 had shadows under mouse pointers, but not menus)
Windows XP analyzes the performance impact of visual effects and uses this to determine whether to enable them, so as to prevent the new functionality from consuming excessive additional processing overhead. Users can further customize these settings. Some effects, such as alpha compositing (transparency and fading), are handled entirely by many newer video cards. However, if the video card is not capable of hardware alpha blending, performance can be substantially degraded, and Microsoft recommends the feature should be turned off manually. Windows XP added the ability for Windows to use "Visual Styles" to change the appearance of the user interface. However, visual styles must be cryptographically signed by Microsoft to run. Luna is the name of the new visual style that is provided with Windows XP, and is enabled by default for machines with more than 64 MiB of RAM. Luna refers only to one particular visual style, not to all of the new user interface features of Windows XP as a whole. Some users "patch" the uxtheme.dll file that restricts the ability to use visual styles, created by the general public or the user, on Windows XP.
In addition to the included Windows XP themes, there is one previously unreleased theme with a dark blue taskbar and window bars similar to Windows Vista titled "Royale Noir" available as unofficial download. Microsoft officially released a modified version of this theme as the "Zune" theme, to celebrate the launch of its Zune portable media player in November 2006. The differences are only visual with a new glassy look along with a black taskbar instead of dark blue and an orange start button instead of green. Additionally, the Media Center "Royale" theme, which was included in the Media Center editions, is also available to download for use on all Windows XP editions.
The default wallpaper, Bliss, is a photo of a landscape in the Napa Valley outside Napa, California, with rolling green hills and a blue sky with stratocumulus and cirrus clouds.
The "classic" interface from Windows 9x and 2000 can be used instead if preferred. Several third party utilities exist that provide hundreds of different visual styles.

Users in British schools observed the improved ease of use and advanced capabilities – comparing the former to RISC OS and Mac OS, and the latter to Unix.
Removed features
Some of the programs and features that were part of the previous versions of Windows did not make it to Windows XP. CD Player, DVD Player and Imaging for Windows are removed as Windows Picture and Fax Viewer, Windows Media Player and Windows shell take over their duties. NetBEUI and NetDDE are deprecated and are not installed by default. DLC and AppleTalk network protocols are removed. Plug-and-play–incompatible communication devices (like modems and network interface cards) are no longer supported.
Service Pack 2 and Service Pack 3 also remove features from Windows XP but to a less noticeable extent. For instance, Program Manager and support for TCP half-open connections are removed in Service Pack 2. Energy Star logo and the address bar on taskbar are removed in Service Pack 3.
Editions
The two major editions are Windows XP Home Edition, designed for home users, and Windows XP Professional, designed for business and power users. XP Professional contains advanced features that the average home user would not use. However, these features are not necessarily missing from XP Home. They are simply disabled, but are there and can become functional. These releases were made available at retail outlets that sell computer software, and were preinstalled on computers sold by major computer manufacturers. A third edition, called Windows XP Media Center Edition, was introduced in 2002 and was updated every year until 2006 to incorporate new digital media, broadcast television and Media Center Extender capabilities. Unlike the Home and Professional edition, it was never made available for retail purchase, and was typically either sold through OEM channels, or was preinstalled on computers that were typically marketed as "media center PCs".
Two different 64-bit editions were made available. One, designed specifically for Itanium-based workstations, was introduced in 2001 at around the same time as the Home and Professional editions, but was discontinued a few years later when vendors of Itanium hardware stopped selling workstation-class machines due to low sales. The other, called Windows XP Professional x64 Edition, supports the x86-64 extension. x86-64 was implemented first by AMD as "AMD64", found in AMD's Opteron and Athlon 64 chips, and later implemented by Intel as "Intel 64" (formerly known as IA-32e and EM64T), found in some of Intel's Pentium 4 and later chips.
Windows XP Tablet PC Edition was produced for a class of specially designed notebook/laptop computers called tablet PCs. It is compatible with a pen-sensitive screen, supporting handwritten notes and portrait-oriented screens.
Internet Explorer 6 running in Windows XP Tablet PC Edition 2004
Microsoft also released Windows XP Embedded, an edition for specific consumer electronics, set-top boxes, kiosks/ATMs, medical devices, arcade video games, point-of-sale terminals, and Voice over Internet Protocol (VoIP) components. In July 2006, Microsoft released Windows Fundamentals for Legacy PCs, a thin client version of Windows XP Embedded which targets older machines (as early as the original Pentium). It is only available to Software Assurance customers. It is intended for corporate customers who may wish to upgrade to Windows XP so they can take advantage of its security and management capabilities, but cannot afford to purchase new hardware.
Editions for specific markets
Windows XP Starter Edition is a lower-cost edition of Windows XP available in Thailand, Indonesia, Russia, India, Colombia, Brazil, Argentina, Peru, Bolivia, Chile, Mexico, Ecuador, Uruguay, Pakistan and Venezuela. It is similar to Windows XP Home, but is limited to low-end hardware, can only run three programs at a time, and has some other features either removed or disabled by default. Each country's edition is also customized for that country, including desktop backgrounds of popular locations, localized help features for those who may not speak English, and other default settings designed for easier use than typical Windows XP installations. The Malaysian version, for example, contains a desktop background of the Kuala Lumpur skyline.
In March 2004, the European Commission fined Microsoft €497 million (US$603 million) and ordered the company to provide a version of Windows without Windows Media Player. The Commission concluded that Microsoft "broke European Union competition law by leveraging its near monopoly in the market for PC operating systems onto the markets for work group server operating systems and for media players". After unsuccessful appeals in 2004 and 2005, Microsoft reached an agreement with the Commission where it would release a court-compliant version, Windows XP Edition N. This version does not include the company's Windows Media Player but instead encourages users to pick and download their own media player. Microsoft wanted to call this version Reduced Media Edition, but EU regulators objected and suggested the Edition N name, with the N signifying "not with Media Player" for both Home and Professional editions of Windows XP. Because it is sold at the same price as the version with Windows Media Player included, Dell, Hewlett-Packard, Lenovo and Fujitsu Siemens have chosen not to stock the product. However, Dell did offer the operating system for a short time. Consumer interest has been low, with roughly 1,500 units shipped to OEMs, and no reported sales to consumers.
In December 2005, the Korean Fair Trade Commission ordered Microsoft to make available editions of Windows XP and Windows Server 2003 that do not contain Windows Media Player or Windows Messenger. Like the European Commission decision, this decision was based on the grounds that Microsoft had abused its dominant position in the market to push other products onto consumers. Unlike that decision, however, Microsoft was also forced to withdraw the non-compliant versions of Windows from the South Korean market. This decision resulted in Microsoft's releasing "K" and "KN" variants of the Home and Professional editions in August 2006.
That same year, Microsoft also released two additional editions of Windows XP Home Edition directed towards subscription-based and pay-as-you-go pricing models. These editions, released as part of Microsoft's FlexGo initiative, are used in conjunction with a hardware component to enforce time limitations on the usage of Windows. Its target market is emerging economies such as Brazil and Vietnam.
Languages
Windows XP was available in many languages. In addition, MUI packs and Language Interface Packs translating the user interface were also available for certain languages.
ATMs and Vendors
Automated teller machine (ATM) vendors Wincor Nixdorf, NCR Corporation and Diebold Incorporated have all adopted Microsoft Windows XP as their migration path from OS/2. Wincor Nixdorf, which has been pushing for standardization for many years, began shipping ATMs with Windows when they first arrived on the scene.
Diebold initially shipped XP Home Edition exclusively, but following extensive pressure from customer banks to support a common operating system, it switched to support XP Professional to match its primary competitors, NCR Corporation and Wincor Nixdorf.
Redbox DVD Vending machines run a modified version of XP designed for the fullscreen User Interface of the Vending Touchscreen and the DVD vending itself.
Service packs
Microsoft occasionally releases service packs for its Windows operating systems to fix problems and add features. Each service pack is a superset of all previous service packs and patches so that only the latest service pack needs to be installed, and also includes new revisions. However if you still have the earliest version of Windows XP on Retail CD (without any service packs included), you will need to install SP1 or SP2, before SP3 can be installed. Older service packs need not be manually removed before application of the most recent one. Windows Update "normally" takes care of automatically removing unnecessary files.
Windows XP was 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. Service Pack 2, Service Pack 3, and Internet Explorer 8 addressed some of these concerns.
The service pack details below only apply to the 32-bit editions. Windows XP Professional x64 Edition was based on Windows Server 2003 with Service Pack 1 and claimed to be "SP1" in system properties from the initial release. It is updated by the same service packs and hotfixes as the x64 edition of Windows Server 2003.
Service Pack 1
Service Pack 1 (SP1) for Windows XP was released on September 9, 2002. It contains post-RTM security fixes and hot-fixes, compatibility updates, optional .NET Framework support, enabling technologies for new devices such as Tablet PCs, and a new Windows Messenger 4.7 version. The most notable new features were USB 2.0 support and a Set Program Access and Defaults utility that aimed at hiding various middleware products. Users can control the default application for activities such as web browsing and instant messaging, as well as hide access to some of Microsoft's bundled programs. This utility was first brought into the older Windows 2000 operating system with its Service Pack 3. This Service Pack supported SATA and hard drives that were larger than 137 GB (48-bit LBA support) by default. The Microsoft Java Virtual Machine, which was not in the RTM version, appeared in this Service Pack. It also removed the Energy Star logo from the ScreenSaver tab of the Display properties, leaving a very noticeable blank space next to the link to enter the Power Management control panel. Support for IPv6 was also introduced in this Service Pack.
On February 3, 2003, Microsoft released Service Pack 1a (SP1a). This release removed Microsoft's Java virtual machine as a result of a lawsuit with Sun Microsystems.
Service Pack 2
Service Pack 2 (SP2) was released on August 25, 2004, with an emphasis on security. Unlike the previous service pack, SP2 added new functionality to Windows XP, such as WPA encryption compatibility and improved Wi-Fi support (with a wizard utility), a pop-up ad blocker for Internet Explorer 6, and partial Bluetooth support. The new welcome screen during the kernel boot removes the subtitles "Professional", "Home Edition" and "Embedded" since Microsoft introduced new Windows XP editions prior to the release of SP2. The green loading bar in Home Edition and the yellow one in Embedded were replaced with the blue bar, seen in Professional and other versions of Windows XP, making the boot-screen of operating systems resemble each other. Colors in other areas, such as Control Panel and the Help and Support tool, remained as before.
Service Pack 2 also added new security enhancements (codenamed "Springboard"), which included a major revision to the included firewall that was renamed to Windows Firewall and became enabled by default, Data Execution Prevention, which can be weakly emulated, gains hardware support in the NX bit that can stop some forms of buffer overflow attacks. Also raw socket support is removed (which supposedly limits the damage done by zombie machines). Additionally, security-related improvements were made to e-mail and web browsing. Windows XP Service Pack 2 includes the Windows Security Center, which provides a general overview of security on the system, including the state of antivirus software, Windows Update, and the new Windows Firewall. Third-party anti-virus and firewall applications can interface with the new Security Center.
Service Pack 3
Windows XP Service Pack 3 (SP3) was released to manufacturing on April 21, 2008, and to the public via both the Microsoft Download Center and Windows Update on May 6, 2008.
It began being automatically pushed out to Automatic Update users on July 10, 2008. A feature set overview which details new features available separately as stand-alone updates to Windows XP, as well as backported features from Windows Vista, has been posted by Microsoft. A total of 1,174 fixes have been included in SP3. Service Pack 3 can be installed on systems with Internet Explorer versions 6, 7, or 8. Internet Explorer 7 and 8 are not included as part of SP3. Service Pack 3 is not available for the 64 bit version of Windows XP.
Processor limits
The maximum total number of logical processors in a PC that Windows XP supports is: 32 for 32-bit; 64 for 64-bit.
The maximum number of physical processors in a PC that Windows XP supports is: 2 for Professional; and 1 for the Home Edition.
Risk
Microsoft is warning users that, after it would discontinue support, users running Windows XP will risk unmitigated zero-day attacks because of reverse engineered security patches for newer Windows versions.
Market share
According to web analytics data generated by Net Applications, Windows XP is currently the second most-used OS with a market share of 28.98%. It has held the number two spot since July 2012.
According to web analytics data generated by StatOwl, Windows XP has a 27.82% market share as of November 2012, having dropped to second place in October 2011.
According to web analytics data generated by W3Schools, from September 2003 to July 2011, Windows XP was the most widely used operating system for accessing the w3schools website, which they claim is consistent with statistics from other websites. As of September 2013, Windows XP market share is at 13.5% after having peaked at 76.1% in January 2007.
ITKiDuniyaa Explains Windows XP (eXPerience) In Simple Words
Microsoft Windows XP was introduced in 2001 and is the most significant upgrade to the Windows operating system since Windows 95. The previous version of Windows, called Windows Me (or Millennium Edition) still had the look and feel of Windows 95 and was known to have stability issues and incompatibilities with certain hardware.
Windows XP addressed many issues of its predecessor and added a number of other improvements as well. It is a stable operating system since it is built on the Windows 2000 kernel, which is known for its reliability. XP also has a new, more modern look, and an interface that is more easy to navigate than previous versions of Windows. While not written from the ground up, like Mac OS X, Windows XP is a substantial system update. The letters "XP" stand for "eXPerience," meaning the operating system is meant to be a new type of user experience.
Windows XP, which is available in Professional version and a Home Edition version, will no longer be supported by Microsoft after April 8, 2014. Although PCs can continue to run Windows XP after that date, they may become more vulnerable to viruses and other security risks.
Microsoft recommends that their customers should consider purchasing a new computer if their old computer running XP is not capable of upgrading to Windows 8.1.
ITKiDuniyaa Explains Windows XP (eXPerience) In Short Words
An operating system introduced in 2001 from Microsoft's Windows family of operating systems, the previous version of Windows being Windows Me. Microsoft called the release its most important product since Windows 95. Along with a redesigned look and feel to the user interface, the new operating system is built on the Windows 2000 kernel, giving the user a more stable and reliable environment than previous versions of Windows. Windows XP comes in two versions, Home and Professional. The company has focused on mobility for both editions, including plug and play features for connecting to wireless networks. The operating system also utilizes the 802.11x wireless security standard.
The "XP" in Windows XP stands for "eXPerience."
