This mite help some one.

A wile ago i posted a question about Notification Area that no body
gave me information about.
So i came to this https://www.codeproject.com/Questions/467637/NotifyIcon-always-show-icon
where - Rokas Gustys - had the same problem as mine.

I found this
https://hianz.wordpress.com/2012/07/13/modify-windows-7-notification-area/

So here is the source for Delphi 10... using BCHexEditor.
I did not change the registry only read it.

I tested it in window 7

program Tray_Notification;

uses
Vcl.Forms,
Main in 'Main.pas' {Form1};

{$R *.res}

begin
Application.Initialize;
Application.MainFormOnTaskbar := True;
Application.CreateForm(TForm1, Form1);
Application.Run;
end.

unit Main;

interface

uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants,
System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.Grids, BCHexEditor,
BCHexEditorEx, Vcl.ExtCtrls, Vcl.ComCtrls, Vcl.Menus;

type

TForm1 = class(TForm)
Button1: TButton;
Label1: TLabel;
Label2: TLabel;
BCHexEditorEx1: TBCHexEditorEx;
BCHexEditor1: TBCHexEditor;
Panel1: TPanel;
Label3: TLabel;
Panel2: TPanel;
ListView1: TListView;

Button2: TButton;
Label5: TLabel;
Label6: TLabel;
procedure Button1Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure Button2Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;
Buff: array of byte;
AList: array of array of byte;

implementation

{$R *.dfm}
uses Registry, Printers;
