• While I agree with your general point, how is it illegal? If I download the ISO from windows, install and keep using it without activation? They aren’t blocking me from using it and I haven’t circumvented any prevention they have in place. What’s illegal here?

    • If they make it easy for you doesn’t mean it’s legal.

      It’s illegal to use windows without a license. As even stated in the license you agree before installing the os, this one, on section 5 Authorized Software and Activation.

      You are authorized to use this software only if you are properly licensed and the software has been properly activated with a genuine product key or by other authorized method
