Solution 2: It is recommended that you switch to visual stdio 2017. Official website can be installed online. visual stdio does not have ISO. http://www.visualstudio.com/downloads/download-visual-studio-vs. Then in the next SDK https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk

Ultimate skill: Redo the system.!
