windows 10 – Trying to change the startup sound

I am trying to change my startup sound, but I am not making it work.
It plays the default sound, but I have no chance of making it play a different sound.

What I have tried:

  • modification of the keys HKEY_CURRENT_USER AppEvents EventLabels WindowsUnlock, WindowsLogoff and WindowsLogon
  • change sounds in the sounds menu
  • replace the Windows Startup.wav files in the windows directory (make a backup first)

I have successfully changed my shutdown sound, my startup sound just won't change.
