I have installed Windows Driver Kit (WDK) 8.1 and according to [this link](http://msdn.microsoft.com/en-us/library/windows/hardware/hh454232%28v=vs.85%29.aspx), in Visual Studio, in the Project Properties frame, at `Platform Toolset`, I should have `WindowsKernelModeDriver8.1`, but it doesn't appear there and according to [this link](http://msdn.microsoft.com/en-us/library/windows/hardware/hh439665%28v=vs.85%29.aspx), at New Project window, I should have `Windows Driver` at installed templates, but, on my Visual Studio, it doens't appear in that list.

I am using Visual Studio Ultimate 2012.

What should I do to add WDK features to Visual Studio?

In addition, if I am checking the macros, more exactly `$(WindowsSDK_IncludePath)`, it included only `...\include\um`, `...\include\shared`, `...\include\winrt`, without `...\include\km` which has all the headers which a device driver needs.
