It was an option bro.
You know one update has to be install is MS update KB 4580364 is required.

i notice when i can't connect to games my xbox power button flashes, then i have to hold down the bluetooth button on the controller to reconnect to windows.
Other than that, i cant help because i don't know what your computer specs or is it connected to bluetooth, or actually what's happening so i am provided with not much info.
Good luck!
