Is there a way to install a newer compiler to an older version IDE (VS 2012)?

I just started learning C++ very recently. The IDE that I am currently using is Visual Studio 2012 which I used to code in C previously, but the compiler that comes with it lacks support for C++11. Plus, the place I am in has limited internet access, so its kind of a pain to install a new IDE (VS 2015 Community is out btw). So is there a way to keep the old IDE and instead just update the compiler in it to use the new standards? I have a feeling that we can't do that, or else they can't sell their new products but I just wanted to be sure. Thanks.
