The registry stores information necessary to configure the system for applications and hardware devices. The registry also contains information that the operating system continually references during operation.
Customizing Device Sound
Files
The operating system uses the registry to locate wave resources in a DLL for system sounds. These sounds can be customized by adding a new resource DLL containing customized sounds, and then adding a registry entry to use these new sounds.
You can customize sound effects with the registry subkey HKEY_LOCAL_MACHINE\Drivers\Builtin\WAPIMAN\Clicks.
The following code example shows how this registry subkey can be used to load custom sounds from a resource DLL, in this case WavClick.dll:
