So when it comes to using newer C++ functionality you will still be stuck on the VS 2010 level even if you are using VS 2012 and if you are using any VS2012 improvements you will not be able to compile for XP.

The analogous statement for VS2013 and its v120_xp holds as well. All
the (half-working) new C++11/14 features in 2013 are available when
targetting XP.

You might have been conflating it with the old WSDK and WDK, which
bundled its own compilers.
