Use the same code like in your question "How to close all?", just with this adjustment :

procedure TMainForm.Button1Click(Sender: TObject);
var I: byte;
begin
LockWindowUpdate(Handle);
if MDIChildCount>0 then
  for I := MDIChildCount-1 downto 0 do
  // here we go
  ShowWindow(MDIChildren[I].Handle, SW_RESTORE);
LockWindowUpdate(0);
end;

Your question appears two times (bad network connection while Submit pressed, I guess :-)), you should delete the second one.

Have you locked with MainForm.Handle or just the local scope Handle property ?
