N and KN versions of Windows may have issues starting when not using the Media Feature Pack (XP/Vista, Windows 7, Windows 8, Windows 8.1, Windows 10).
Many games will generate a log file in the installation folder or configuration file location containing details of the error that occurred.
This is usually caused by another program stealing focus, e.g. antivirus (some antivirus programs have a "game mode" that can be used to prevent this). Identify the program, then adjust its settings or disable it. Samsung Magician is known to cause this behaviour.
Games may also switch to windowed mode if an unavailable resolution has been chosen in the game or specified in a configuration file.
