Dear Tester
We would like to invite you to participate in the Microsoft Windows Anytime Upgrade Beta. Windows Anytime Upgrade is a feature of the Windows Vista operating system that helps enable consumers of Windows Vista Home Basic, Windows Vista Home Premium or Windows Vista Business editions to purchase and upgrade online to a higher edition of Windows Vista in order to enjoy additional features.
Note: The beta will only be tested for the upgrade scenario of Home Premium to Ultimate. Therefore we need you to install Home Premium in order to start the upgrade process.
