So, due to Microsoft's intention this is no longer a thing. For users' convenience it could auto-download Windows 8, Windows 10, and Windows 11 from the Internet and write it to your removable drive. It turns the complicated process of making a USB stick with Windows into a few clicks. Rufus is the most popular tool for making bootable medias. As of now, the feature is not available in Rufus. The developer expects a long time before a solution comes into play and will make possible to download ISOs again. It has been updated to version 1.30 that informs the user that the download is now blocked by Microsoft.

Technically Rufus relies on the Fido script to get the download done. If I understand the situation right, Microsoft now checks the referrer data to determine from where the download request comes, and blocks it if it doesn't come from.

The change now affects the popular Rufus tool, which can't now download Windows 8, Windows 10 and Windows 11. So it has silently made a change to servers that host Windows ISO files. Looks like Microsoft isn't happy with third-party tools that replace and extend features of its very own Media Creation Tool.
