i want to disable all types of sounds permanently so the user will not be able to hear any kind of sound in future. since I have uninstalled sound drivers from Device Manager but on restarting PC , It gets automatically installed again.
Don't delete the drivers, Disable them instead. They stay installed but not used. Right click on the sound devices and select disable - They should all be under 'Sound, Video and Game controllers' (Windows 7/8)
