Start by finding the Visual Studio 2017 folder on the Start Menu and click on the entry for Developer Command Prompt for VS2017. This will start a Windows command prompt and set up the environmental variables to use Visual C++ 2017. However, rather unhelpfully, it will also leave the command line in the Visual Studio folder under the Program Files folder. If you intend to do any development, you will want to move out of this folder to one where creating and deleting files will do no harm. Before you do that, move to the Visual C++ folder and list the files:
C:\Program Files\Microsoft Visual Studio\2017\Community>cd %VCToolsInstallDir%C:\Program Files\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.0.10.2517>dir ...
