Windows XP (codenamed Whistler) is an operating system developed by Microsoft, released to manufacturing on 2001-08-24 and to general availability on 2001-10-25. It is the sixth operating system in the Windows NT operating system line, succeeding Windows 2000 and preceding Windows Vista. It also succeeded Windows ME after the end of the Windows 9x kernel. It is one of Microsoft's longest lasting operating systems, with almost 13 years of support (both mainstream and extended) and still runs on 1.29% of desktop and laptop computers worldwide as of 2020-01.

Main changes[edit | edit source]

User interface[edit | edit source]

Windows XP got a major UI overhaul during development, with the introduction of Themes. Users could change the way windows and buttons looked with the new visual style, Luna. It had three color schemes, which were based on blue, green and silver. Users could still select the Windows Classic theme from previous versions of Windows (98, 2000, ME, ...), and customize the preset Windows Classic color schemes.

The introduction of ClearType, an anti-aliasing font function allowed easier text reading on desktop computers with LCD-TFT monitors and laptops, but also had an effect on CRT monitors.

The taskbar is locked by default for new user accounts, to prevent accidental resizing or moving of the taskbar and/or the toolbars. Multiple instances of an application are grouped automatically and inactive tray area icons are hidden automatically, to prevent cluttering of the taskbar.
