Why I am getting "The Windows SDK version 8.1 was not found" error, when building my C++ application in with Visual Studio 2017?

You are getting "The Windows SDK version 8.1 was not found" error, because you forgot to install Windows SDK version 8.1 on your computer.

Here are the steps to reproduce the error:

1. Create a new project and select "Win32 Console Application" type.

2. Click "Build > Build Solution" menu. You see the following compilation error:

1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE
   \VC\VCTargets\Platforms\Win32\PlatformToolsets\v141\Toolset.targets(34,5): 
   error MSB8036: The Windows SDK version 8.1 was not found. Install the required 
   version of Windows SDK or change the SDK version in the project property 
   pages or by right-clicking the solution and selecting "Retarget solution".

1>Done building project "Hello-Project.vcxproj" -- FAILED.
