WindowsSDK_IncludePath macro missing

Question

Just like the title says.

I go to project properties -> VC++ Directories -> Include Directories -> Macros>>

It's not in that list at all. The result is that VS cannot open Windows.h. How can I reset this macro to its default value (or set it at all)?

Answer 1

That variable should be set by the installation of the Windows SDK. You likely just need to reinstall it (here is the link for 8.1: https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx).
