Where can I download Windows 8 legally, from Microsoft?
A few weeks ago, I purchased and installed Windows 8 Pro as an upgrade from Windows 7 (Ultimate). I didn't format my system drive, so I kept all my settings and applications. Everything went fine.
The process was entirely handled through Microsoft's assistant (purchasing, downloading, installing), though, and I don't think a backup ISO copy (or something like that) of Windows 8 was ever saved somewhere on my system.
I am now considering replacing my system hard drive with a SSD drive, and I think it'd be a good idea to do a clean install at the same time. But like I said, I don't have an install disc or even an ISO file for Windows 8, so I'm a bit at a loss about how to proceed. I searched the web and the W8 official site without finding much success.
What are my options? Is it possible to download W8 it from Microsoft (I searched but found nothing), or do I have to reinstall Windows 7 (for which I have the disc) and then re-do the upgrade process? Or something else?
