I was surprised I was able to uninstall Media Player on Windows 11. I played a video file on my laptop and accidentally selected "always open with". Lo and behold Windows Media Player doesn't play HEVC encoded files (not sure if it was 264 or 265). I thought I would have to tinker with the default program settings but tried "add or remove programs" on a lark and it worked. I then opened the file with VLC as one normally does and life is back in balance.
