that is awesome. i wish windows was like that. it has basic integrated drivers but never graphic or sound card drivers for real hardware.
and welcome to the world of modern OSs.
windows is so bloated and wasteful.
dont think of anything that you are doing in terms of Windows. Dont think of drivers or even firmware for that matter.
just use the device. if it needs an update (whether its an app or an OS revision) just update it. simple.
dont overthink it. you've crossed that bridge already.
enjoy your device.
