Where is Maximise button?

Maximize Buttons The maximize button in Windows is the middle button with the square. In the Mac, the green plus sign (+) is officially the "zoom button," and it expands the window to a pre-set size, not the entire screen.

Oh! I found in object inspector "BorderIcons" Just set there biMaximize from true to false!

Here is another trick if you want to do it using code only.

procedure TForm1.FormCreate(Sender: TObject);
var
  l: DWORD;
begin

  // hide minimize and maximise buttons
  l := GetWindowLong(Self.Handle, GWL_STYLE);
  l := l and not(WS_MINIMIZEBOX);
  l := l and not(WS_MAXIMIZEBOX);
  l := SetWindowLong(Self.Handle, GWL_STYLE, l);

end;
