While new owners of low-cost and ultra-portable computers can still get Windows XP pre-loaded through 2010, Microsoft has required distributors of XP to pull all copies off of the shelves June 30. However, Microsoft did leave the door open to all computer makers, even the largest, who want to continue selling new PCs with XP preinstalled. "Additionally, Systems Builders (sometimes referred to as 'local OEMs'), may continue to purchase Windows XP through Authorized Distributors through January 31, 2009," repeating existing policy that lets small-sized computer builders obtain XP from dealers like Ingram Micro.
