A bit worrying folks are still using Windows 7 with no support or security updates from now on.. Move to Windows 10 after 5 years it's now almost usable. Windows 10 still looks 1995 graphics but Microsoft took a major step back from windows 7 with 8 and 10.
Personally I understand your view (it's still a view, I know lots of people who very much dislike Windows 10 look and feel), but you're forgetting the "drivers" problem with Windows 10. There are quite a number of hardware devices out there (several popular soundcards for instance) that don't have Windows 10 drivers. If you, as a small radiostation, have a card that was expensive back in the days and you still want to use it, migrating to Windows 10 isn't an option.
Again, I don't want to stimulate older Windows versions, but Windows 7 with RadioDJ and no other usage/programs and in an controlled environment isn't the biggest risk. If I got $1 for every system out there in a critical environment with Windows XP, OS/2 or even DOS... I would give Marius a job to able to work on RDJ and still wouldn't need to work for the rest of my life...
