Is there a possibility and I’m not talking about breaking patents or anything like that, but I’m talking about a possibility technically, to have a Linux OS that can run Windows 11 apps natively?
No bottles or ports, just download an EXE file and run it.
Maybe you would be interested in ReactOS which is an operating system built from scratch to be compatible with Windows.
As for your question, you could probably make it so that it look like Linux is handling Executable files natively, but behind the scene you can’t get away from having something that convert Windows system calls into Linux system call.
