Here is an example........
---------
interface

uses
  SysUtils, Windows, Messages, Classes, Graphics, Controls,
  Forms, Dialogs;

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
    function HookProc(var Message: TMessage): boolean;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

const
  FlagFileName = 'C:\Flag.Fil';

procedure CreateFlagFile;
var
  F: System.Text;
begin
  System.Assign(F, FlagFileName);
  System.Rewrite(F);
  Writeln(F, 'This is a dummy flag file');
  System.Close(F);
end;

procedure KillFlagFile;
var
  F: File;
begin
  System.Assign(F, FlagFileName);
  System.Erase(F);
end;

procedure MyExitProc; far;
begin
  KillFlagFile;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.HookMainWindow(HookProc);
end;

function TForm1.HookProc(var Message: TMessage): boolean;
begin
  Result := false;
  if Message.Msg = WM_EndSession then
  begin
    if WordBool(Message.wParam) then
    begin
      { Windows is closing down - clean up!! }
       Halt;
    end;
  end;
end;

initialization
  CreateFlagFile;
  AddExitProc(MyExitProc);
end.

When Windows 95 shut down it will shut all applications and process so that if you write Delphi program to detect windows shut down and close all other applications; it dosn't mean any thing becuase windows automaticly shut down this programs when it shut down.
