If you don't know where your "license" for the upgrade is, then...
From Microsoft...
"A personal digital locker is created for you when you purchase a Windows
Vista upgrade. Your digital locker stores your product keys and purchase
information which, when used together, allow you to reinstall your upgrade
if necessary. A copy of your upgrade is also stored in your digital locker.
To access your upgrade in your digital locker for recovery:
Click Start, and then click Control Panel. Double-click the digital locker
icon. Alternatively, you can go directly to the Digital Locker website.
