As per the support lifecycle policy introduced by Microsoft in 2002, all Microsoft‘s business and developer products go out of support after 10years.
The 10 years of support consisting of 5 years mainstream support and 5 years extended support. So, the support for Windows XP and Office 2003 will end on April 8, 2014.
What does it mean to the existing customers?. After April 8, 2014 Microsoft will not release any new security updates, non-security hotfixes, free or paid assisted support options or even online technical content updates. This will make the existing customers vulnerable to security threats.
Microsoft advices all the existing Windows XP SP3 and Microsoft Office 2003 customers to migrate the systems to Windows 7 and Office 2010.
Microsoft provides the Microsoft Deployment Toolkit to help customers to accelerate and automate deployments of Windows 7 and Microsoft Office products.
