    I had 2 no brand name desktops with XP Prof OEM installed without visible product key and 1 HP notebook with Vista OEM with product key. Will Window 7 home premium family upgrade works in this case? In other word, will upgrade work with the desktop pc without product key label on the case?

    Any help would be greatly appreciated.
