title: Get a screenshot of desktop in full screen 3D-application
body: <p>Is it possible to render the desktop into a screen shot when using a full screen 3D-application (such as a game)? Or does windows close the rendering engine while the game is running? </p>
  
  <p>I am looking for ways to render the desktop into a texture in my game. Can RDP like protocols be a solution?</p>
  
  <p>Edit: To clarify, is there any deep level api mechanism to force rendering into another buffer such as when screen shots are made. Doesn't matter if it is only windows 7 or Windows 8/9.</p>
