Since I started this thread, I might share some more improvements.
In this Update I managed to get the PID of the current process and
in the future I hope the HelloWorld program process could be
killed,
I'm kind of stuck right now on how.
Right now a complete Command Line command to compile HelloWorld
example with a working Command Line Interface looks like this:
dmd HelloWorld.d whatever.res && start "" "HelloWorld.exe"
whatever.res - look at above posts on how to generate whatever.res
HelloWorld.d
import std.stdio : write, writeln, readln, writefln;
import std.process : executeShell, kill, thisProcessID;
import core.thread.osthread : getpid;
void main() {
executeShell("title HelloWorld");
executeShell("chcp 65001");
writeln("Hello, World!");

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/enrmidvsfdugqmudo...@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 ICONDISCARDABLE "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.
Also, if you want some kind of Fancy ASCII art in your
application:
Look at the Google for any ASCII Art generator:
http://patorjk.com/software/taag/#p=display=Elite=Hello%20World
Add this line and insert your ASCII art in a writeln function.
executeShell("chcp 65001");
to your D language program source code
More about chcp can be found here: https://ss64.com/nt/chcp.html
Or here:
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/chcp
import std.stdio : write, writeln, readln;
import std.process : executeShell;
void main() {
executeShell("title HelloWorld");
executeShell("chcp 65001");
writeln("Hello, World!");

you might enjoy using my terminal lib
https://code.dlang.org/packages/arsd-official%3Aterminal
include that and set
"subConfigurations": {
"arsd-official:terminal": "builtin_emulator"
}
and it gives you a gui window that acts like a terminal.
then in your program, here's a complete program you can run with
dub run --single file.d
/+ dub.sdl:
name "cool"
dependency "arsd-official:terminal" version=">=7.2.0"
subConfiguration "arsd-official:terminal"
"builtin_emulator"
+/
import arsd.terminal;
void main() {
auto terminal = Terminal(ConsoleOutputType.linear);
terminal.setTitle("whatever");
// this is possible too but you MUST have an indexed png which
might be hard to make if you aren't ready for it.
terminal.changeWindowIcon("your_icon.png");
terminal.writeln("hi");
auto got = terminal.getline("say something: ");
terminal.writeln("you said ", got);
}

As the simplest solution, you can set the window title in
shortcut properties.
It seems that all the Command Prompt Batch command of windows
such as "title" do work well.
By using executeShell I was able to change the title of the
Command Line that runs my program.
import std.stdio : write, writeln, readln;
import std.process : executeShell;
void main() {
writeln("Hello, World!");
executeShell("title HelloWorld");
string line;
while ((line = readln()) !is null)
write(line);
}
import std.file : mkdir;
It would be great if we could change/customise the icon of the
Command line application that run the HelloWorld application. But
I have a bad feeling that it is probably not possible without a
GUI library.

If you do not want to create the library yourself, you could
spawn a terminal application like konsole or kitty and start a
simple cli app.
You'd need to have some form of inter process communication
setup for this though.
On Windows 10, this example, when compiled and clicked on the
executable - spawns a command line with the "Hello World" output
shown.
import std.stdio;
void main() {
write("Hello, World!");
string line;
while ((line = readln()) !is null)
write(line);
}
The important question is: how can we change the name/title of
this Command Line application.
