Microsoft releases SP2c to allow system builders to keep cranking out XP machines
Microsoft Corp. has had to create a new build of Windows XP Professional for computer makers because the six-year-old operating system's continued popularity has nearly exhausted the supply of product activation keys.
The new build, dubbed SP2c, includes no fixes or feature changes, but was created simply to address the shrinking pool of product keys. XP Pro SP2c, which has been released to manufacturing, will be made available to resellers and system builders next month, said Microsoft.
