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

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

does LockWindowUpdate(Handle); make a app hang sometimes?
Have you locked with MainForm.Handle or just the local scope Handle property ?
