Microsoft released Windows XP and Office XP in 2001, a version that aimed to encompass the features of both its business and home product lines. The release included an updated version of the Windows 2000 kernel, enhanced DOS emulation abilities, and many of the home-user features found in previous consumer versions. XP introduced a new graphical user interface, the first such change since Windows 95. The operating system was the first to require Microsoft Product Activation, an anti-piracy mechanism that requires users to activate the software with Microsoft within 30 days. Later, Microsoft would enter the multibillion-dollar game console market dominated by Sony and Nintendo, with the release of the Xbox. The Xbox finished behind the dominant PlayStation 2 selling 24 million units compared to 155 million overall; however they managed to outsell the GameCube which sold 21 million units. Microsoft launched their second console, the Xbox 360, in 2005 – which was more successful than the original. By 2017 the Xbox 360 had sold 84 million units but failed to outsell its main rival the PlayStation 3 which sold 87 million units when discontinued. The console was also outsold by the Wii which introduced gesture control and opened up a new market for video games. Microsoft later used their popular controller-free Kinect peripheral to increase the popularity of the Xbox. This was very successful. Kinect was the fastest selling consumer electronics product in history. It sold 8 million units from November 4, 2010, to January 3, 2011, (its first 60 days). It averaged 133,333 units per day, outselling the iPhone and iPad over equivalent post-launch periods.
