Good morning to all,
To make Hans' work easier, it would be time for some of you to skip the Windows XP page, for technicians and engineers (Broadcasting, studio, etc...) it doesn't look very serious, and complicate the developer's work. I only recommend Windows version 7, 8.1 update 3, and 10. bar point!
As a (hobby) programmer I understand what you're saying, but fact is that Windows XP is still pretty widely used in the broadcasting scene. And why not? Not supported anymore? If it's not broken, don't fix it. Also if it's not connected to the Internet it's not for security reasons.
If you want to do things officially, you're just telling broadcasters who have hardware that still functions good to pull out their wallet and buy a new license. Also, don't forget the driver change Microsoft made when going from XP to Vista; there is (audio) hardware out there that isn't supported anymore from Vista onwards.
Personally, I don't use XP anymore for quite some time, but I can understand that there is a group out there that still does - and it's not a real minority...
