Windows SAPI error : 'GetVersionExA': was declared deprecated - c++

Question

So all I want in life is to have a program where I can say "Hey Computer" and it responds with "Hello". So I set myself upon the task and after some research produced the code below yet whenever I try to compile it through Visual Studio 2017 on Windows 10 I get this error: 'GetVersionExA': was declared deprecated but I don't understand because I don't call that function anywhere in my code.

Answer 1

It is suppressable with a pragma:
#pragma warning(disable:4996)
#include <sphelper.h>
#pragma warning(default: 4996)

Answer 2

GetVersionEx is being used by the header sphelper.h which you're including. It's using it to check that the function SpGetDescription() is running on Vista or later. You could probably work around this issue by targeting the 8.1 SDK version instead of 10. However, it's bad that the shipped MS SAPI API in the Windows 10 SDK is using functions which are deprecated in Windows 10.. I'd say this is a MS issue.
Alternately this would work:
#define FKG_FORCED_USAGE 1
#include <sphelper.h>
#undef FKG_FORCED_USAGE
