Re: Future of XP Professional x64
If you read our Lifecycle FAQ (
http://support.microsoft.com/gp/lifepolicy)
you see that we only offer Extended Support for "Business and Developer
products" not "Consumer, Hardware, and Multimedia products". There's some
internal debate about whether or not Ultimate should be treated as a
"Consumer" or a "Corporate" SKU when it's designed to be the union of the
two, so that's likely why the webpage lists "N/A" for Ultimate. That could
well change depending on how many business & developer customers end up
standardizing on Ultimate instead of Business/Enterprise.
In any case, remember that the Microsoft Support Lifecycle only applies to
Windows itself. Microsoft will provide updates for the OS, and under
Extended Support Microsoft will continue to provide updates and support but
in some cases will require a paid extended hotfix agreement. Microsoft
product teams are free to stop supporting a version of Windows once it
leaves "Mainstream Support", and third party suppliers of software,
hardware, and applications are free to do whatever they want. The incentive
marketing programs like the Windows logo programs are built with "Mainstream
Support" in mind, and typically are silent on the need to support down-level
versions of Windows. There's nothing in the Works With Windows Vista,
Certified for Windows Vista, or Games for Windows programs that says it has
to work on anything except Windows Vista. These programs do not preclude
supporting older versions, but they don't mandate it either.
