My Xbox Controller moves my mouse cursor under Windows 10, so I have problems in some games like Fifa and Rocket League.
The controller worked flawlessly for 2 years without moving the cursor.
Suggestions for solutions from the internet advise you to switch off xbox configurations support under steam. This has been switched off for some time.
Other suggested solutions were to deactivate one of them two "HID-compilant mouse" drivers which did not help.
Any other options? The problem is now for 2-3 weeks and came out of nowhere.
Disconnect the connection under Settings - reconnect devices and again. You can also try to set your own layout for the controller in the control settings.
