I have been considering updating my Windows 7 Pro machine to Windows 10 for a while now, but I am wondering if the below is possible. . .
Before I go through the bother of updating and possibly having to restore back to 7 Pro if something goes wrong, or if my system simply doesn’t like Windows 10, I do happen to have a perfectly good 500GB drive lying around. Can I download the Windows Media Creation Tool and an ISO of Windows 10 and install it on that drive? That way I can simply plug the existing drive back in if something is not right. So, can I still get an ISO, and if yes, how long can I test it before I must enter a license key?
Also, if I can do that, will there be a problem when I re-install my original drive and update to Windows 10 (assuming it works correctly)?
