Vista upgrade workaround revealed
C|Net | at | by Mike
An IT professional claims to have discovered a way of upgrading to a full version of Vista from scratch, while only paying the cost of an upgrade for an earlier version of Windows.
Marc Liron has posted a full explanation of his method on his Web site. In summary, the trick is to install the upgrade version of Vista but not to enter the product key. Once all the Vista files have been copied across, the user starts the installation procedure again rather than attempting to activate Vista. Once the installation procedure has been followed again, the user is left with a fully functioning version of Vista.
