📝 Notes

MPC-HC registers associations for a wide range of video/audio formats: .mkv, .mp4, .avi, .mov, .wmv, .flv, .ts, .m2ts, .mp3, .flac, .ogg, and more.
The portable version writes no registry keys — settings go to mpc-hc.ini alongside the .exe.
RememberLastPos = 1 stores per-file playback positions in a separate registry subkey Recent File List.
