None of above worked for me, except Kai's. I modified his answer: I added 'btn_close.IsCancel = true;' to constructor. SettingsWindow is my second window, and main window is (default) MainWindow.

  public partial class SettingsWindow : Window {
    public SettingsWindow() {
      InitializeComponent();
      btn_close.IsCancel = true;
    }
    private void btn_close_Click(object sender, RoutedEventArgs e) {
      this.Close();
    }
  }
