The Home Premium, Professional, and Ultimate editions of Windows Vista were successful, with 1% market share compared to 4% for earlier versions of Windows. In 2009 Microsoft reported 640 million licenses of Windows Vista sold, and 3.8 million licenses of Windows XP were sold. By April 2011, Microsoft had sold over a billion licenses of Windows Vista through retail, and since mid-2008, Windows Vista received security and performance updates, while Windows XP was cut off by Microsoft in April 2009, and no further updates were released for it. The company reported extending the Windows XP support life cycle by eight years, until April 14, 2014. As of March 2010, there were around 890 million copies of Windows XP still in use. As of December 27, 2012, 332 million copies of Windows 7, and 199 million copies of Windows 8, were in use, compared to the 16.1 million of Windows 8.1; while many copies of Windows XP were replaced with Windows 7 or Windows 8, both Microsoft's next version, Windows 9, will not support Windows XP. Many reviewers and industry insiders heavily criticized Windows Vista for long operating system updates after its release in 2006, and its poor support and uptake of hardware, as well as citing performance and usability issues.
Windows Vista Home Premium was Microsoft's most affordable personal computer operating system made available at retail; its hardware requirements include a processor with a minimum clock speed of 1.8 GHz, a minimum of 1 gigabyte of random-access memory, a minimum of 20 gigabytes of disk, and a graphics card with 128 MB or greater of video memory. New versions of hardware are required for those running Microsoft's Windows Vista Service Pack 1, released in 2007. However, any graphics card and motherboard capable of running Windows Vista can be used, even if they were previously used for Windows XP. In May 2008, an MSDN version of the same product came with the new Microsoft Security Essentials Anti-Virus suite preinstalled. d2c66b5586
