Windows XP

For pre-release wallpapers and pictures, see Whistler. Windows XP, codenamed Whistler, is an operating system released by Microsoft in 2001. It is the successor to Windows 2000 and Me, being the first version of Windows NT intended for both businesses and home users. It has a memorable set of wallpapers, sample pictures and user account pictures, including the iconic Bliss, one of the most viewed photos on Earth due to it being the default wallpaper and XP's popularity. Also notable are Red moon desert, taken by Bliss' Charles O'Rear, Autumn, which was the subject of a Vanity Fair article and the branding wallpaper. It would be followed by Windows Vista in 2006, after years of its messy development.

Wallpapers
According to Windows XP's program manager Gregory Raiz, the wallpapers of XP were selected "to evoke natural themes of hills, trees & sand", as Microsoft aimed for XP to look and feel more human than previous versions. The wallpapers were primarily licensed from Corbis and used a mix of royalty free and rights managed licenses, while Bliss was fully acquired from Corbis and Charles O'Rear so that no company would ever use it again. With the exception of Vortec space, the non-photographic wallpapers were created by various contractors that worked internally at Microsoft, according to Raiz through email correspondence.

Like with Windows 2000, the wallpapers are at a rather low resolution of 800x600, which became rather outdated not long after XP was released, due to screen resolutions progressively increasing. Downloadable wallpapers would later be provided in higher resolutions, while Windows Vista onwards features wallpapers at 1920x1440 and 1920x1200.

Media Center Edition-exclusive
As Media Center Edition came with many features of Microsoft Plus! for Windows XP, its wallpapers were also included alongside the standard set, albeit with new names that reference what is depicted in the wallpaper. Most of these wallpapers appear to have been taken from Getty Images, although some were presumably taken down many years ago, leaving their origins unclear. Unlike with XP's wallpapers, these appear to have went under noticeable edits.

Starter Edition
Starter Edition was only released in developing countries such as Latin American countries, Russia and Turkey. Each localized version of Starter Edition has around three to six wallpapers depicting national landmarks, and does not include the standard wallpaper set. Most of them come from Corbis and Getty Images and use a rights managed license, with a few being royalty free. Similar to the Home and Professional editions of Windows XP, these wallpapers have a resolution of 800x600 (with the exception of one being 801x600, likely by accident). Unlike these two editions, however, Windows XP Starter Edition includes wallpapers in the Bitmap (.bmp) file format instead of the JPEG (.jpg) file format. The practice of having regional wallpapers would be used again by Microsoft for Windows 7, where 20 countries received two themes (built-in and downloadable) consisting of six wallpapers each.

The default wallpaper is SE_neutral_wallpaper, which is completely unrelated to the default wallpaper used in most other editions. Also, due to the rarity of XP Starter Edition in several countries, not all wallpapers are known so they cannot be listed. Starter Edition was also released in sub-Saharan African countries, possibly also Egypt and other developing countries too, although no ISOs or even photos are known to exist. The Chinese release appears to have been cancelled.

Embedded Standard and POSReady 2009
In 2008, Microsoft released newer embedded versions of XP. POSReady 2009 features three wallpapers: one with no logo, one with a small logo and one with a large logo. [table will be done soon]

Sample pictures
Compared to 2000 and Me which featured one sample picture, XP features a selection of four. All four were royalty free Corbis images, three of which were available from royalty free CDs, with the other one seemingly being online only. Similar to the wallpapers, all of these images have a resolution of 800x600.

Media Center Edition-exclusive
Windows XP Media Center Edition adds five new images to accompany the standard selection, which are also royalty free Corbis images. Like a few Windows 7 Beta sample pictures, these wallpapers retain the aspect ratios of the original images (usually around 3:2). Rather than using 800x600 like the original four sample pictures, they appear at various 3:2-ish resolutions, all 1280px wide.

User account pictures
XP was the first version of Windows to include selectable user account pictures to represent the user. A mix of royalty free Corbis images and PhotoDisc images, including a few rights managed Corbis images, all having a resolution of 48x48, comprise the Windows XP user account picture choices. A few of them appear to have edited background colors from the original images, possibly to create more contrast between the background and object. Many of these also appear in several versions of Windows Live Messenger, albeit at a slightly higher resolution of 96x96.
