title: Hide Window from taskbar without using WS_EX_TOOLWINDOW
body: <p>I have a main Window and an About Window, The About Window is opened from the main Window, but the problem is that the About Window is shown in the taskbar! </p>
  
  <p>I have found that in order to hide a Window from the taskbar, I can use the <code>WS_EX_TOOLWINDOW</code> style, but I don't want the About Window to have this style, so is there another way to do it?</p>
