You needn't reinstall Windows, as you should be able to change your product
key via System Properties. To do this:
1. Click Start, right click Computer and click Properties
2. Go to the bottom of the window, and click Change Product Key.
3. If a UAC prompt comes up, click Allow or enter in your Admin password.
4. Change your product key to the Vista Ultimate product key.
5. Do as it tells you to.
