Microsoft is slowly phasing Windows XP out as all the focus is now on Windows 7. "As announced in April 2008 - on October 22, 2010, OEMs will no longer be able to pre-install Windows XP Home on new netbook PCs. However for a majority of customers, they mayn't notice much change; many PC makers have already been actively manufacturing & selling Windows 7 netbooks since it release. According to NPD's Retail Tracking Service, by April 2010, 81% of netbook units sold at retail in US came with Windows 7 pre-installed," revealed Brandon LeBlanc.
"I would also like to remind people who're still running Windows XP that as of July 13th, 2010, XP SP2 will also reach the end of support. You'll need to install Windows XP SP3 via Microsoft Update website or look at moving to Windows 7 to be running a supported version of Windows. Support for Windows XP SP3 will continue through April 2014," LeBlanc added.
