The end of mainstream support by Microsoft for Windows XP ended on April 14. That deadline came and left with barely an audible groan from the minions of enterprise, small business and consumer users of the decade-old operating system. The steadfast legions of corporate Windows XP users — and the Microsoft Office 2003 suite that also is no longer supported — are not facing any dire consequences for not migrating to Windows Vista and the Office 7 suite, however. No doomsday alarms have sounded.
