Am Einfachsten geht's so:
Delphi-Quellcode:
// uses ShellApi
procedure TForm1.bnSoundClick(Sender: TObject);
var FN : String;
begin //SOUND = shell:::{F2DDFC82-8F12-4CDD-B7DC-D4FE1425AA4D}
FN:='shell:::{F2DDFC82-8F12-4CDD-B7DC-D4FE1425AA4D}';
ShellExecute(0,nil,PChar('explorer.exe'),PChar(FN),'',SW_SHOWNORMAL);
end;
