I tried it 2 weeks ago. My FSX would shut down around the two hour mark. Not good on a cross country flight. I tried everything that I knew to remove all rest and sleep times, nothing helped. FSX also did not want to run in the full screen view which I had to keep switching back. Some of the FSX menu could not be seen in the reduced screen view. I rolled back to Windows 7 and happy again. Windows 10 is great if you like Apps.
