As a matter of fact, Windows XP will end of support by this April 8, 2014. If you haven't started planning to migrate your Windows XP PCs to a modern OS, perhaps the “Deploying Windows 7” course that had published in Microsoft Virtual Academy (MVA) is useful for you. This course originated in the Deployment Learning Portal (DLP). While the DLP itself has been phased out, it will continue to live within the MVA and in the 10 languages.
In the course, they provide you step-by-step guide to each step in the Windows 7 deployment process from application compatibility testing and volume activation to image creation and data migration.
By the end of the track, you will have gained an understanding of the tools, processes, and best practices that will help make your Windows 7 deployment a success.
To learn more about deployment for Windows 7, you can also always visit to The Springboard Series Blog and the Windows 7 Deployment Zone.
Accordng to the Microsoft Lifcycle website (I cannot link it due to an error it creates on posting) XP has extended support until April 8th 2014. But this trainig is still very useful.
