I have the iPega-9076. I don't know if the 9083 works in the same way or not, so can only share my experiences with my model.
The 9076 supports xInput on windows, but defaults to a PS3 controller. You have to hold down turbo for 3 seconds after connection to switch it to switch it to xInput mode.
The 9076 doesn't support connection to a PC via Bluetooth, however. Bluetooth work when connection to Android devices, but to connect to a PC you need to either use a cable, or the built in 2.4Ghz wireless receiver.
