A Microsoft official said the company has no plans to extend Windows XP's looming retirement date in order to give companies whose business systems run on the aging OS more time to migrate to a newer version of Windows--and that could be a problem for those who have yet to begin the transition.

"There's absolutely no chance" that Windows XP's April, 2014 end-of-life date, when Microsoft will end all support, will be extended, said Rich Reynolds, general manager for Windows Commercial marketing, in an interview.
