I only installed Win11 in one VM and therefore can't look for the WMP.DLL at the moment. But when I look at the path to the DLL, I notice this: microsoft-windows-mediaplayer-core and that leads us here: https://learn.microsoft.com/en-us/uw...ew=winrt-22621 So this WMP.DLL is a UWP/WinRT DLL. If you only want to play audio, you can also use the WinRT class MediaPlayer from Win10: https://learn.microsoft.com/en-us/uw...ew=winrt-22621
