New Lenovo ideapad P400 came with Win 8 loaded. How do I change it to Win 8 pro or Win 8 Enterprise? Do I need to use the Win 8 Enterprise ISO (burned to DVD) and do the install or can I Just change the Product Key to Win 8 enterprise? Does the product key determine the features to turn on? Is the base code for Win 8 the same for all versions? or Do I need to specifically use the Enterprise DVD and do an install or update?
Also Where does the Lenovo Laptop get the product key from? The install did not ask for a Key. How do I activate? Lenovo does not provide documentation containing Win 8 product key.
