It looks like isorecorder not available since a while ago. May I remove it from the list in w.d.o/faq/CD index page?
At the same time, rufus (https://rufus.ie/
) should be mentioned as a great app on Windows to make bootable usb stick from iso (GNU licensing, source code available on GitLab).
Please cc me on the answer, I'm not a member of this list, but you can find me on debian-www.
