Как добавить свой пункт меню?

function AddMenuItem(ConnType: TconnType; MenuText, StatusBarText,
  GuidOrPath: string; HelpMenu: Boolean): string;
var
  GUID: TGUID;
  ID: string;
  Reg: TRegistry;
begin
  CreateGuid(GUID);
  ID := GuidToString(GUID);
  Reg := TRegistry.Create;
  with Reg do
  begin
    RootKey := HKEY_LOCAL_MACHINE;
    OpenKey('\Software\Microsoft\Internet Explorer\Extensions\'
      + ID, True);
    if HelpMenu then
      WriteString('MenuCostumize', 'help');
    WriteString('CLSID', '{1FBA04EE-3024-11d2-8F1F-0000F87ABD16}');
    WriteString('MenuText', MenuText);
    WriteString('MenuStatusBar', StatusBarText);
    case ConnType of
      EXECUTABLE: WriteString('Exec', GuidOrPath);
      COM_OBJECT: WriteString('ClsidExtension', GuidOrPath);
      SCRIPT: WriteString('Script', GuidOrPath);
    end;
    CloseKey;
    OpenKey('\Software\IE5Tools\Menu Items\', True);
    WriteString(MenuText, ID);
    CloseKey;
    Free;
  end;
  Result := ID;
end;
