VS2015 fixing path issue in VC_IncludePath - c++

Question

I have a Problem when attempting to compile a simple hello world c++ program.
#include <iostream>
int main()
{
std::cout << "hello world" << std::endl;
return 0;
}
Among the errors is:
cannot open source file "errno.h"
A quick search using the console (c:\> dir errno.h /s) reveals that the file is in multiple directories:
C:\LegacyApp\VisualStudio2013\VC\crt\src
C:\LegacyApp\VisualStudio2013\VC\include
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\crt\src
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include
C:\Program Files (x86)\Windows Kits\10\Include\10.0.10150.0\ucrt
My Project Default Properies Include the following macro:
$(VC_IncludePath);$(WindowsSDK_IncludePath);
This resolves to:
C:\LegacyApp\VisualStudio2015\VC\include
C:\LegacyApp\VisualStudio2015\VC\atlmfc\include
C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt
C:\Program Files (x86)\Windows Kits\8.1\Include\um
C:\Program Files (x86)\Windows Kits\8.1\Include\shared
C:\Program Files (x86)\Windows Kits\8.1\Include\winrt
The folder C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt does not exist on my system.
It seems like I want to switch out the Version 10.0.10240.0 to be 10.0.10150.0
How can I edit the defaults for the macro VC_IncludePath?
Is there an even wiser course of action here?

Answer 1

Seems installation of Windows 10 SDK version 10.0.10240.0 is broken on your machine. You can reinstall it or use the other version installed on your computer.
If Windows 10 SDK version 10.0.10150.0 installed properly you should be able to use it in your VC++ project. To do that change Target Platform Version on General page of you project configuration to 10.0.10150.0. This value should be among the others in dropdown list.
Otherwise reinstall Windows 10 SDK and use the recently installed version.

Look at Working with Project Properties, particularly the section Property Pages.
There is a similar SO question, How do I modify Visual Studio 2015 predefined macros?, with an answer that says modify the file
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Common.props
but I would first try using the intended properties from the first link.
