I want to buy (or get legally for free) a copy of windows 10, but I'm confused.
I see this link: https://www.microsoft.com/en-us/software-download/windows10ISO
It suggests I can get a copy of Windows 10 for free. I see others online saying that gives you the ISO but you still need a key
I'm not sure if I will then need to buy a activation key.
I see vendors selling activation keys.
I'm downloading the ISO from MS as I write this and am not ready to install to find out. Will I need a key?
Is there anything to worry about buying a key from a vendor?
By the way; If install Windows 10, and get it running, will the version above allow upgrade to 11?
