How do upgrade from Windows XP to Vista without buying a full version?
There’re a few articles circulating the web on how to upgrade to a full version of Windows Vista from scratch, and only paying the cost of an upgrade from ealier versions of Windows. This is first reported by Marc Liron on his website. Here’s how it works: • Install the upgrade version of Vista without entering the product key. • Wait until the Vista files have been copied across, start the installation again instead of activating it. • Completed. That’s it. Please keep in mind that this is in violation of Microsoft License Agreement. We highly recommend you to purchase a full version after 30 days trial.
