Microsoft will soon discontinue selling Windows XP through our sales channels. In industry terms this is called "End-Of-Sales" (EOS). The last day Microsoft Authorized OEM Distributors can purchase Windows XP from Microsoft will be January 31, 2009. For major PC manufacturers, this EOS date was June 30, 2008. OEM Distributors can continue to sell Windows XP to their system builder customers subsequent to January 31, 2009, while they work through their existing inventory.
