Q: If I have a Volume License or a subscription to MSDN, should I use this program?
A. Customers with active Volume License Agreements and MSDN subscriptions already have access to Windows XP Professional x64 Edition under their existing plan.
Q: If I have Windows XP Home Edition, Windows XP Tablet PC Edition or Windows XP Media Center Edition, am I eligible for this program?
A: No, the Windows x64 Editions Technology Advancement Program only allows exchanges from one like product to another. Customers with versions of the product other than Windows XP Professional can either upgrade to Windows XP Professional and then make the exchange or purchase the Windows XP Professional x64 Edition CD from a System Builder, Distributor, or pre-installed on a new PC.
Q: If I submit an order for a Windows XP Professional x64 Edition can I return my 32-bit XP Professional Edition?
A: You will not be able to return your 32-bit license of Windows XP Professional. If you are uncertain on making the exchange, we recommend you try the software first by using the Windows XP Professional x64 Edition Trial Software Program.
