Since I upgraded to win 10 pro x64, my FSX and FSX: Steam edition won't shut down completely. I have to use task manager to finish shutting down. I've gone to details and looked at the wait chain, but don't know what it is that fsx is waiting for. The last one was: PID 23500 thread 22364. If any one knows what that means I'd appreciate it. I've even just loaded up fsx, then shut it down after it loaded. This didn't happen in win 7 pro x64. I do have some dream fleet, pmdg and other software, and also ANS 4.1.
