Hello Ray, this is Manuela!. I'm an Independent Advisor ready to assist with this

What TV do you have?
Is this "game mode" message appearing when you open a game on your Xbox one?
Or where you found this "game mode" in your Xbox settings?

I appreciate if you give me more details about your situation

So what you would need to do to stop the automatic downloads to your console is switch your power mode to energy saving here is a support article telling you how to do that.

This will make your console start up take a little longer but it will prevent your game updates from downloading while the console is off.

Think of it this way when:

In instant on mode its like putting a computer to sleep when you turn it back on it just starts up from where you were previously.

In energy saving mode it is like turning your computer completely off and has to go through a full reboot everytime you start it up.

Have you changed the power mode of you xbox so that when you turn it off it is actually turning off, and not going into "instant on" mode?

If it's set to "instant on" mode you can alternatively just hold the power button down on the front of the console for 5 seconds to completely shut down your xbox.

Here is a guide to the power settings, the different modes and how to change them

I had the exact same problem with my XBOX ONE controller. It wouldn't pair for the life of me, but in another computer it worked. Finally realized in the taskbar of the computer that didn't work Airplane Mode was enabled. I turned off airplane mode and
now my XBOX ONE controller will pair again. I hope this helps someone else like me that had no answer for why the controller didn't work for the longest time. Such a simple thing

how about you turn your xbox and your computer off and modern off and see if that will work
