If you choose to purchase an upgrade version of Windows Vista to upgrade XP, you will no longer be able to use that version of XP. Either on another system, or as a dual-boot option. The key will be invalidated, preventing activation.

From Vista’s EULA found here (PDF) :

13. UPGRADES. To use upgrade software, you must first be licensed for the software that is eligiblefor the upgrade. Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from. After you upgrade, you may no longer use the software you upgraded from.

That's pretty bad in and of itself, but combine that with the fact that Vista Upgrade packages can no longer be used to do a clean install and you've got a problem. It means that you cannot re-install Vista Upgrade *ever*. You can't install a clean version and you can't install XP and do an upgrade.

This means that everyone who used Vista Upgrade will have to go out and by Vista Full when they need to reinstall the OS in about a year.

That upgrade provision is nothing new. All upgrade licenses that I have ever seen say something similar.

The real question is this: Does anything specifically prevent you from downgrading back to XP, ie, give up all rights to use Vista and go back to XP?

THAT would be new and awful.

XP had the same clause.
