I want my driver to be supported by Windows Vista. I am using Visual Studio 2015 for development. I have downloaded and installed WDK 10 which supports my driver down to Windows 7. According to this site I need WDK 8 for my driver to be compatible with Windows Vista. After I installed the WDK 8 i cannot set it in Visual Studio.
What is the proper way to integrate WDK 8 into Visual Studio 2015?
WDK 8 can be used till Visual Studio 2012, after that it is not officially supported. Check link

It clearly says that:
We provide Windows Driver Kit (WDK) 8 to give you time to migrate to WDK 8.1 Update and Visual Studio 2013. Microsoft does not support WDK 8 and will make no further updates to this kit. We recommend that you use the latest versions of the WDK and Visual Studio to build drivers for Windows.
Important: You must install Visual Studio Professional 2012 or Visual Studio Ultimate before you install WDK 8.
So for using WDK 8 and driver for Vista you need Visual Studio 2012.
