In 2001, the operating system Windows XP (code name Whistler) was launched on the market, which combined the previously developed separate lines of operating systems for home users (Windows 3.1, 95, 98, Me) and professionals (Windows NT, 2000). Microsoft has used the kernel of Windows NT 5.1 in its new product, which has been migrated to the home users' products, replacing the old 16-bit solutions. Windows XP is Microsoft's longest-serving version of operating systems - it was present on the market from 2001 to 2007, when it was replaced by Windows Vista in the consumer market. Together with SP3, Windows XP was supported by Microsoft until April 8, 2014.
In XP, Windows activation appeared for the first time to prevent piracy. However, it was quickly broken by computer pirates. Windows XP was also the first system to support a 64-bit processor architecture. It was also the first fully multimedia-based system to support TV cards and tuners. Windows XP was supposed to be user-friendly, which proves that it had many useful multimedia applications and interesting solutions already at the start, which were missing in Windows 98 or were commissioned, e.g. in Windows ME. They mainly included integration of multimedia or organizational tasks with the explorer, user switching capabilities, support for LCD and TrueType monitors. Windows XP introduced a new Luna interface, animations, shadows (e.g. cursor, icons), and fully 32-bit icons. The system has gained great success on the market and has been recognized by many as the best ever.
The development of Windows XP started in 1999 under the name Windows Neptune. However, as early as the beginning of 2000, work on Neptune stopped and preparations for the Whistler project started. Work on the system took 18 months, from December 1999 to August 2001. The operating system was launched on October 25, 2001.
