I have a bit of a unique issue. My son is 12 and has autism. The problem is he has his volume way, way up on his PC,(and he wont use earphones.) Does anyone know of any software for Windows 10 that would allow me to lock the volume so he cant turn it up? He knows his way around a PC so it has to be something with a password to gain access to the controls. I used some software called 'Quiet on the Set' which should of been password protected but for some reason, if you restart the PC or switch it off, it would reset and he could turn the volume back up.
