Question

In the main window constructor I tried che

Answer 1

Keyboard.Modifiers is the right class/property to use.

I would suggest checking the modifiers in a handler for the FrameworkElement.Loaded event.

In the Window constructor after InitializeComponent():

this.Loaded += new RoutedEventHandler(Window_Loaded);

And:

void Window_Loaded(object sender, RoutedEventArgs e)
{
    // Examine Keyboard.Modifiers and set fullscreen/windowed
    if ((Keyboard.Modifiers & ModifierKeys.Shift) > 0)
    {
        //SetFullscreen();
    }
}
