For Windows phone??
I wonder why they've changed the driver model yet again. A search suggests it was to support Windows Phone:
https://msdn.microsoft.com/en-us/windows/hardware/drivers/develop/driver-model-convergence
"To make your device work on Windows and Windows Phone releases before Windows 10, you probably needed to write two separate drivers, for example one for Windows 8.1 and one for Windows Phone 8.1. In Windows 10, in most cases, you can write one driver that will run on any Windows 10 version. This topic describes convergence plans for device driver interfaces in Windows 10 and provides details when there are version-specific differences."
What use is a legacy OS if it doesn't support legacy devices? Microsoft, you're going to be toast when Google delivers on Android on the Desktop... assuming Pichai stops faffing around with his Chrome baby and lets the Android developers storm Microsoft final stronghold.
You can't even make minor tweaks without breaking your userbase.
