The program-free program-free execution file after the window is displayed in the file browser is the system default icon. Use ordinary icon view programs (such as: icon sucker), you can find that there is no icon in the execution file. The default icon that can be imagined that the system is displayed is to be added.
Increase method:
Add a resource file in the project -> Add an icon, re-compiling.
Note: This method is completely experimental, no verification of theoretical basis. However, I estimate that the Windows system is the first ICON in the execution file resource when the Windows system is displayed. Knowledge about ICON under Windows can refer to the article "ICONS IN WIN32" in MSDN.
