Splinter Cell Blacklist

Is there anyone who is playing Splinter Cell Blacklist? I am facing a problem while playing the game on my Notebook PC. I've Windows 10 and what problem I'm facing is that when I accidentally go back to the desktop or if I press Alt+TAB and go to the desktop, and when I return back to the game, I couldn't. The game stops responding while I can hear the music of the main menu screen. But can't access the game.

tried using alt-enter to put it in windowed and back?
