Method 1: The Recommended Microsoft Route (Free Dev Essentials)
A: If you hold a valid Visual Studio 2010 license (or MSDN subscription from that era), yes. Otherwise, use the Microsoft SDK (still freeware).
The Windows SDK v7.1 contains the exact command-line compilers and linkers that make up the v100 toolset. This allows you to build C++ applications without installing the heavy Visual Studio 2010 IDE.
