Microsoft to support Windows XP through at least 2014
June 30th is the last day you'll be able to pick up a retail copy of Windows XP. But you will still be able to purchase a computer running Windows Vista Business or Ultimate editions and ask the computer maker to downgrade the system to XP for you. Some PC makers may offer this option for free while others will charge a fee.
Microsoft is also making an exception to the no-sales-beyond-June 30th rule for some low-cost, low-power devices like the Asus Eee PC. So it makes sense for the company to offer a few more years of support. Add to this the fact that Windows Vista adoption has been slow in some sectors, and it honestly seems like Microsoft didn't have much choice but to offer extended support for an operating system that was first released in 2001.
