The Windows 7 Upgrade Program is designed to assist Microsoft's OEM partners in minimizing the number of end users who may postpone acquiring a new computer because of the impending release of the Windows 7 operating system. This program allows OEMs to offer an upgrade to Windows 7 to end users who qualify.
This is a consumer-oriented program targeted at individual consumers and small businesses that have purchased eligible PCs during the Program Eligibility Period. End users will have to meet these requirements to be deemed eligible for the upgrade to Windows 7 when it is released :
End users must purchase a new PC that is pre-installed with an eligible Windows Vista Operating System (OS), during the program eligibility window.
The PC must have a valid Certificate of Authenticity (COA) attached.
The only Windows Vista® versions eligible for the program are :
Windows Vista® Home Premium
Windows Vista® Business
Windows Vista® Ultimate
* Microsoft Windows Vista® Home Basic, Windows Vista® Starter Edition, and Windows® XP (all editions) are not qualifying products under the program.
The Program does not support multiple upgrades for medium, large, or enterprise customers. Customers that want to upgrade multiple PCs should use the appropriate Microsoft Volume Licensing program. See
www.microsoft.com/licensing for more details.
The following are the only valid upgrade paths under the program :
Windows Vista® Home Premium -> Windows® 7 Home Premium
Windows Vista® Business -> Windows® 7 Professional
Windows Vista® Ultimate -> Windows® 7 Ultimate
Do note that this is an optional program, so not all OEMs may choose to participate. OEMs that choose to participate in this upgrade program will have the freedom to determine how to best provide qualifying end users with the details.
