On the second comment in the issue I linked to, I'm describing what's failing. So yes, it's not working at all. There is no need for QA before it's fixed. All you need to do to test it yourself is to enable the open CD option in the menu. I have no plans to look into the issue again which is why I have disabled it, closed the issue and listed it as not supported in the features for Windows. To fix it or look into the issue you need to at least have a Windows PC setup up with a development environment, a debugger and a CD drive which is why I sent you the guide. It's on the bottom of the my TODO list. It's simply not a priority for me considering that most users aren't using strawberry for playing CD's. There are too many others things that needs to be done.
Windows 10 is supported by Microsoft until 2025. All the libraries we use still work with Windows 10. Binaries can be built to work on both Windows 10 and 11 so there isn't more work to support 10. A ton of users are still on Windows 10. I see no reason to drop support for Windows 10 at this point. So I don't know how you came to that conclusion.
