I found this info  here  https://stackoverflow.com/questions/37668692/visual-studio-setting-winver-win32-winnt-to-windows-8-on-windows-7
"VS 2012 uses the Windows 8.0 SDK which defaults to _WIN32_WINNT=0x0602 (Windows 8). VS 2013 / 2015 uses the Windows 8.1 SDK which defaults to _WIN32_WINNT=0x0603 (Windows 8.1). If you use VS 2015 and the Windows 10 SDK, it defaults to _WIN32_WINNT=0x0A00 (Windows 10)."

So it seems you get some more or less recent default when working with a not too old compiler/SDK.
