How to recognize windows lock?

Question

WPF

Hello. How to recognize windows lock and user change in WPF application?

private void Window_KeyDown(object sender, KeyEventArgs e)
        {
            if ((e.Key == Key.LWin || e.Key == Key.RWin) && e.Key == Key.L)
            {
                MessageBox.Show("Остановка");
            }
        }

This option is not suitable. Does not work. Can you somehow find out what state windows is in? Without reading data from the keyboard?
