I have Windows 7 pro 32 bit but need to take advantage of more memory so want to upgrade to ultimate 64 bit. I'm a student and have seen that I can get an upgrade to ultimate 64bit but it says that I cannot do this from Windows 7 at all but can do it from vista business - as per below link Windows 7 Ultimate: Microsoft Windows 7 Ultimate 64-bit edition
Do you know this to be the case? I have a vista busines recovery disc but am unsure if this will actually install the vista os on my notebook (I have all data that I need backed up on a USB removable hdd so not bothered if it's a clean install). I really need to do this legitimately as the reason I need to upgrade is so that I can install and run virtual machines to do a microsoft course (quite ironic) and would get found out immediately if I didn't choose the correct way to do it.
Any advise would be great - Thanks in advance
