As if the Vista Upgrade version wasn’t bad enough already, compared to previous Windows Upgrades, now a blogger named (or known as) Blair is reporting that the Windows XP will become invalid which then prevents you from ever using Windows XP again.

Here’s a quote from Microsoft’s Vista EULA:

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.

Do they really want consumers to upgrade, or are they just trying to alienate everyone?
