when i first started reading all the info on win7 one thing that i read was that all the 7 versions were on the install disc and that you got a licence for the one that you paid for such as 7 home premium and if later on i wanted to upgrade to 7 professional all i had to do was pay whatever the cost of the upgrade was and they give you a licence key for that new upgrade and bam, there it was already installed and ready to go. does anyone know if that is the case or does one have to buy a completly new version to upgrade from 7 home premium to 7 professional??
thanks
