Today is the Last Day for Windows Anytime Upgrade

"Saturday, July 3 is the last day Windows Anytime Upgrade (WAU) can be used in the U.S. for upgrading Windows 7 on a new PC. WAU gives purchasers of PCs the opportunity to upgrade their version of Windows 7 to a more feature rich edition. This can be done through retail channels, but WAU offers an extra discount."

If you are in the US, today is your last shot.  So before you start celebrating the long holiday weekend do yourself a favor and cure any of your computers of Windows 7 Starter.
