    vcvarsall.bat [option] store
  or
    vcvarsall.bat [option] [version number]
  or
    vcvarsall.bat [option] store [version number]
where [option] is: x86 | amd64 | arm | x86_amd64 | x86_arm | amd64_x86 | amd64_arm
where [version number] is either the full Windows 10 SDK version number or "8.1" to use the windows 8.1 SDK

The store parameter sets environment variables to support
  store (rather than desktop) development.

    vcvarsall.bat x86_arm store
    vcvarsall.bat x86_amd64 10.0.10240.0
    vcvarsall.bat x86_arm store 10.0.10240.0
    vcvarsall.bat x64 8.1
