var
  Reg: TRegistry;
begin
  Reg := TRegistry.Create;

      OpenKey('\CLSID\' + CLSID_ContextMenu + '\InProcServer32', True);
      WriteString('', ExtractFilePath(Application.ExeName) + '\Project1.dll');

      CreateKey('\Directory\Background\ShellEx\ContextMenuHandlers\' + CLSID_ContextMenu);

Answer 1

I found it! In XP i wrote to

\Directory\Background\Shell**Ex**\**ContextMenuHandlers**\CLSID

but in Windows 7 the path should be like

\Directory\Background\Shell\Name of your app\command

and in command we put a path to our app in double quotes “%path%”.:)
