I'm a university student in the UK and I can get a free copy of Windows 8 Professional (I'm getting the 64-bit version of course) through DreamSpark but I have some questions: 1) What type of license is it? OEM or retail? Upgrade or full? Does it require the PC to have Windows XP/Vista/7 already installed or can I do a clean install? 2) There are two identical versions available, the only difference is that one is "English" and the other "English - Great Britain". I assume the only difference is that the second has British English and there's no ther difference right? 3) Does buying it through DreamSpark mean that my key will not be valid once I graduate (because I'm not a student anymore)? 4) Are offers on DreamSpark permanent or do they expire after some time? I'm planning to buy Windows 8 later, perhaps after a Service Pack 1, so I would like to get directly the SP1 version. 5) If instead I buy it now, after the release of a possible Service Pack 1, would I be able to get the SP1 ISO replacing my "normal" Windows 8? 6) Will the ISO be always available to download? So if I misplace my DVD I still could be able to install it. Thanks.
