The Xbox One controller's loses pairing

hooked up the controller from the xbox one s to PC through wireless receiver on windows 7, everything works, seems like xinput and I had to disable the check for digital signatures in group policy. If a test, the controller was not working and the driver was raised, or rather were set, but worked properly, burning exclamation point

connect a USB cable (defined not as Xinput, but as a HID-compatible device), everything is OK, but after the cable is disconnected, the controller does not pair the phone with the receiver. On the Microsoft website say to update the firmware but the app is only available on Windows 10

On Windows 7 it is normal that you lose the pair and should be put in the category of upgrade the firmware? How you do this?

the problem is actually not a problem, because if the controller gets connected to charge through the USB cable that goes to the power supply and connect is also through the receiver, just wondering
