Main editions

Home & Professional Diagram representing the main editions of Windows XP, based on the category of the edition (grey) and codebase (black arrow) The first two editions released by Microsoft are Windows XP Home Edition, designed for home users, and Windows XP Professional, designed for business and power users.

Windows XP Professional offers a number of features unavailable in the Home Edition, including:Comparing Windows XP Home Edition and Windows XP Professional Feature Differences. The ability to become part of a Windows Server domain, a group of computers that are remotely managed by one or more central servers. An access control scheme that allows specific permissions on files to be granted to specific users under normal circumstances. However, users can use tools other than Windows Explorer (like cacls or File Manager), or restart to Safe Mode to modify access control lists. Remote Desktop server, which allows a PC to be operated by another Windows XP user over a local area network or the Internet. Offline Files and Folders, which allow the PC to automatically store a copy of files from another networked computer and work with them while disconnected from the network. Encrypting File System, which encrypts files stored on the computer's hard drive so they cannot be read by another user, even with physical access to the storage medium. Centralized administration features, including Group Policies, Automatic Software Installation and Maintenance, Roaming User Profiles, and Remote Installation Services (RIS). Internet Information Services (IIS), Microsoft's HTTP and FTP Server. Support for two physical central processing units (CPUs). (Because the number of CPU cores and simultaneous multithreading capabilities on modern CPUs are considered to be part of a single physical processor, multi-core CPUs are supported using XP Home Edition.) Windows Management Instrumentation Console (WMIC): WMIC is a command-line tool designed to ease WMI information retrieval about a system by using simple keywords (aliases). The ability to switch hard disk storage type from Basic to Dynamic and vice versa.

Edition N In March 2004, the European Commission fined Microsoft €497 million (£395 million or $784 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.

The N editions of Windows XP also do not include Windows Movie Maker, but Microsoft has made this available as a separate download.

K & KN 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.

The K and KN editions of Windows XP Home Edition and Professional Edition were released in August 2006, and are only available in English and Korean. Both editions contain links to third-party instant messenger and media player software.

Home Edition ULCPC This edition of Windows XP Home is intended for sale with certain "low-cost" netbooks and will appear labeled as "Windows XP Home Edition ULCPC" on the back of the netbook (with "ULCPC" standing for "ultra-low-cost personal computer"). This edition contains a regular license of Windows XP Home Edition with Service Pack 3 included.

Professional Blade PC Edition This version comes preinstalled on OEM solutions providing desktops on Blade PC hardware. In addition to a copy of Windows XP Professional, it includes a Remote Desktop License.

Starter edition

Windows XP Starter is a lower-cost version of Windows XP available in Thailand, Vietnam, Turkey, Indonesia, India, Philippines, Russia, Colombia, Brazil, Argentina, Peru, Bolivia, Chile, Mexico, Ecuador, Uruguay, Malaysia, and Venezuela. It is similar to Windows XP Home Edition, but is limited to low-end hardware, can only run 3 programs at a time, and has some other features either removed or disabled by default.

According to a Microsoft press release, Windows XP Starter is "a low-cost introduction to the Microsoft Windows XP operating system designed for first-time desktop PC users in developing countries."

Specialization The Starter edition includes some special features for certain markets where consumers may not be computer literate. Not found in the Home Edition, these include localized help features for those who may not speak English, a country-specific computer wallpapers and screensavers, and other default settings designed for easier use than typical Windows XP installations. One such setting is both the desktop icons and the mouse cursor size are set to large to assist new computer users.

In addition, the Starter edition also has some unique limitations to prevent it from displacing more expensive versions of Windows XP:

Only three applications can be run at once on the Starter edition, and each application may open a maximum of three windows. If a user tried to open more, a dialog message box would pop up reminding them of this limitation. This also helped the computer from getting overloaded with lots of open windows and programs as Windows XP Starter is licensed only for low-end processors like Intel's Celeron or AMD's Duron and Sempron. There is a 512 MB limit on main memory and a 120 GB disk size limit. Microsoft has not made it clear, however, if this is for total disk space, per partition, or per disk. The maximum screen resolution is 1024×768, originally 800x600. There is no support for multiple user accounts. Windows Setup creates a user account automatically. There is no support for securing the user account with a password. Upon machine startup, Windows XP Starter will auto logon. PC-PC networking, joining a domain, and sharing printers across a network is not supported. Classic view in the control panel is not supported. Only one wallpaper is included by default, but localized versions contained more wallpapers and screensavers related to the locale. The Malaysian version, for example, contains a desktop background of the Kuala Lumpur skyline. There are fewer options for customizing the themes, desktop, and taskbar. It notably does not ship with the Luna theme enabled and the only theme available is the Windows Classic theme. The file is, however, present and can be activated by changing registry settings. To remind users that they are using Windows XP Starter, there is a persistent watermark in the lower right hand corner of the screen that is visible at all times. This watermark is similar in behavior to the Windows activation watermark in Windows 10.

Market adoption On October 9, 2006, Microsoft announced that they reached a milestone of 1 million units of Windows XP Starter sold. In the mass market, however, the Starter edition has not had much success. In many markets where it is available, pirated versions of higher end versions of Windows are more popular than their legal counterparts. In these markets, non-genuine copies of XP Professional can be obtained at a mall. These stores typically charge only for the amount of the CDs/DVDs taken up by the files, not the original retail value. Unlicensed copies of Windows XP Professional typically cost 70¢, since it only uses 1 CD, compared to around $30 for a properly licensed copy of XP Starter.

Media Center Edition

This edition, which was code-named "Freestyle" during its development, was first released in September 2002. The initial release was available solely in conjunction with computers that included media center capabilities, and could not be purchased separately. The first major update was released in 2004 and distributed by Tier 1 OEMs who had previously sold Windows XP Media Center Edition PC, and then updated again in 2005, which was the first edition available for System Builders. Many of the features of Windows XP Media Center Edition 2005 (including screen dancers, auto playlist DJ, and high end visual screen savers) were taken from the Windows XP Plus! packages. These were originally shipped as add-ons to Windows XP to enhance the users experience of their Windows XP machine.

It adds support for the Xbox 360 as a media center extender, DVB-T broadcasts, and support for two ATSC tuner cards.

After the 2005 release, Microsoft focused their efforts on building new media center features into "Home Premium" and "Ultimate" editions of Windows Vista and Windows 7, which have Windows Media Center built-in and, unlike the releases of Windows XP Media Center Edition, were available for retail purchase without the necessary hardware.
