The increase in customer demand for Windows XP has prompted some system builders, such as Dell to re-offer Windows XP on their new systems

To meet with this unexpected increase in demand Microsoft have had to release a new version of Windows XP Professional because it has run out of product license keys for the 32 bit version . Windows XP Service Pack 2c (SP2c) has been produced to provide new copies of the Operating System for system builders and does not provide any additional features. More details can be found on a TechNet Blog

Microsoft still plans to phase out Windows XP, which will only be available for sale to everyone except system builders until 31 January 2008, however, system builders will still be able to offer the operating system on new builds until 31 January 2009 when it will become unavailable altogether.
