Windows beenden und dabei Updates installieren

[TUX_der_Pinguin]

Zitat von boeseboese:

Hallo,

wäre evtl. jemand so freundlich das geschilderte Programm in der kompletten endgültigen Fassung zu quoten, so dass man es seinem Compiler vor die Füße werfen kann?

Danke und Gruß

Hier ein kleines Programm welches nur den Rechner veranlasst herunterzufahren. Es sollten dann auch die Updates installiert werden.
Im Anhang befindet sich die Projekt Dateien samt Quelltext und EXE-File.

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm15 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form15: TForm15;

implementation

uses Unit2;

{$R *.dfm}

procedure TForm15.Button1Click(Sender: TObject);
begin
  WindowsShutDown(nil, nil, 0, True, False);
end;

end.
