  4. Hi,

    I have a Win7 Professional RTM installation DVD (downloaded from an academic support site).

    I’d like to flatten my recently bought laptop and put win 7 on while I wait for my legit copy of Home Premium (OEM upgrade offer) to be delivered… then just pop in the product key and activate it as Home Premium – all above board. Would this work, i.e. will it downgrade itself or would it be a case of “can’t do that.. i’m Win 7 professional” ?

    any help appreciated
