Yeah I've had this issue too. Microsoft is just an absolutely relentless spyware organisation now. They want to stop the use of ALL legacy versions because it's not spyware/virus ridden.
I even managed to get Windows 8 installed on a Windows 10 laptop but they've managed to block all drivers from getting installed. About 20 devices in device manager with no drivers, even after manually downloading the drivers windows would only pretend to install them. Sorry but you don't stand a chance with Windows 7.
But when I installed windows 10 it was ALL automatic lol. All 20 devices had their drivers automatically installed.
