Troubleshooting

All mouse and key input goes to the Android device

In my case, while connected, all mouse and key input goes to the Android device. There was no way to get any input to Windows 10 without stopping the session. To keep local controls it helped for me to disable full screen at this point. Go with your mouse cursor to the right-top. A taskbar becomes visible. Click the arrows to disable the full screen.
