In what's installed on your system? No. No difference. Obviously ISO is slightly different with converted esd. core/pro versions only have single index file dates might be off for the iso contents. Also the wim will have a different xml identifier and possibly different size None of those things that are different about the iso will affect what's installed to your computer.
So these have both versions? Would it give some sort of choice on a clean install? On an upgrade would it also give a choice or would it just upgrade the correct free version?
And then when GA comes and possibly new ISO from MSDN, we do it again. Gotta collect em all. pokemon.jpg
ESD does, ISO will. but to satisfy my curiosity, where you get this kind of nonsense and what edition you saying will not? Ill test that theory this instant.
