Windows 7 Upgrade or Anytime Upgrade?

What's the difference between a Windows 7 upgrade and an Anytime Upgrade? A Windows 7 upgrade is an upgrade from an older version of Windows, like Windows Vista or Windows XP. The anytime upgrade is an upgrade from one version of Windows 7 to another version of Windows 7. For example, you can use Anytime Upgrade to go from Windows 7 Home Premium to Windows 7 Ultimate. You can see which version of Windows 7 you are running by clicking the Start button, then right-clicking on Comptuer and choosing Properties from the right-click menu or by pressing the Windows key and the Pause key at the same time.
