Vista Invalidates XP Keys
Windows Vista's official launch has brought to light problems that were largely hidden during its development, multiple sources said on Tuesday. Windows XP users upgrading to the new OS have learned that the user agreement (PDF) for upgrade editions of Vista contains a clause that sees Vista's license supercede that of XP, porentially invalidating the installation of the old version -- which is now technically necessary for the Vista upgrade. "Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from," the document says. "After you upgrade, you may no longer use the software you upgraded from."
While Microsoft is likely to allow installations of the earlier Windows version for Vista upgrades in at least the near future, the decision creates potential complications for those forced to reinstall the software as activation codes may cease to function at a later date.
