Microsoft really wants its customers to migrate to Vista or Windows 7. The following is an official statement from Microsoft:
It?s important to remind customers that Microsoft are still planning to retire XP Pro Mainstream support on April 14, 2009 and will only provide OS security updates beyond that date unless the customer has an Extended Hotfix Support contract.So if you haven't upgraded, it may be time to do so, or you'll end up with a deadbeat OS.
