Hello Berg II, Michael,
yes, Windows supports Windows Media Player Legacy, but it is no longer the default application in newer versions of Windows. In Windows 10 and Windows 11, Windows Media Player is still available, but Microsoft has introduced Windows Media Player 12 as the latest version.
For users who need or prefer an older version of Windows Media Player (legacy), it can still be installed and used, but with limited functionality. In newer versions of Windows, such as Windows 11, Windows Media Player is increasingly being replaced by the Films & TV app and Microsoft Edge for media playback.
If you need a specific version of Windows Media Player or want to run an older application, this may be possible by enabling Windows features or using compatibility modes.
If this is helpful, please accept the answer. Thank you.
