Forever thankful to Adam D. Ruppe
It is possible to embed icon into the Windows executable.
The Original Adam's thread: 
https://forum.dlang.org/post/enrmidvsfdugqmudokdz@forum.dlang.org

The instructions:
Download a valid Windows 3.0 icon resource
Examples: 
http://files.alexmeub.com.s3.amazonaws.com/other/win98_icons.zip

Download the tools to embed the Icon for the .exe executable.
http://ftp.digitalmars.com/bup.zip

Create a new text file named whatever.rc with the content similar 
to this:

> IDI_ICON1       ICON    DISCARDABLE     "iconfil.ico"

Use rcc.exe tool and whatever.rc file to generate whatever.res 
file.
> rcc.exe whatever.rc

Use dmd.exe compiler to embed newly created whatever.res file 
into your .exe file while compiling:
> dmd.exe whatever.res

You should see that the newly compiled .exe file is now with an 
Icon.
And when launched the icon will be used by the Command Prompt.
