I accessed the url https://www.microsoft.com/en-gb/software-download/windows10ISO from my mac and got this page
Clicking the button pointed out by the red arrow starts downloading the iso file.
However, when I accessed the same url from my win10 machine, I got anther page
where I can only download a burn-iso-to-usb tool.
How do I download win10 iso from a win10 machine?
