Hi, I've recently encountered a problem in windows media player on a windows 10 machine that I can't figure out the reason or solution for. Simply put, any playlist that is renamed will revert to it's original name after about 3 hours. This happens regardless of whether it is renamed in media player, or if the playlist file itself is renamed in file explorer. It doesn't seem to make a difference if the program or even the system is restarted during that time, playlists maintain their new names even a complete restart, but only until the 3 hour time limit is up. I don't understand what causes this. If it was a setting in media player, shouldn't it just stop the playlists being renamed or revert them on startup? If it's some form of file protection in windows, the same argument could be made. Any suggestions would be much appreciated.
