When installing the operating systems (clients) onto the Paragon Partition Manager machine (host), what are the license requirements for the clients? For instance, say I have a Vista Home 32 bit, Windows 7 Home Premium 32 bit and Windows 7 Home Premium 64 bit o/s installed on the machine. Does each operating systems need to be authorised and licensed even though each one is only being active one at a time? Of course, i'm speaking from a Microsoft legal aspect not from a "what can I get away with" aspect. Any info that anyone can give me would be appreciated. Thanks.
