Where do I download Windows 7 (legally from Microsoft)?
Where I can I legally download Windows 7 installation .ISO files?
I want to upgrade my Windows 7 32-bit to Windows 7 64-bit because I'm fed-up with the memory limitations. I have a valid Windows 7 key, which based on a search of SO, should be valid for 64-bit. The issue I have, is I don't have a 64-bit ISO. I know Microsoft used to have TechNet downloads of all the OS ISOs, but I can't find them.
I understand that some might scream 'piracy', but I have a completely valid, purchased key and I assume asking for the ISO is completely legal and doesn't contravene any SU rules. Can anyone direct me on how to get a 64-bit ISO?
Help is appreciated.
-- I was told that the 32-bit ISO allowed 64-bit installation, this isn't the case with the ISO I have at least. But if this can be done, tips on how to do it would be great :)
