About Windows shutdown:

  TForm1 = class(TForm)
    { Private declarations }
    procedure WMQueryEndSession (var Message: TMessage); message WM_QUERYENDSESSION ;
    { Public declarations }

  Form1: TForm1;


{$R *.DFM}

procedure TForm1.WMQueryEndSession(var Message: TMessage);
  // do your stuff here
  Message.Result := Integer(true);

Forgot to say that TForm1 is your main form. The code above is for your main form only.

When I close an app with the Task manager (Windows XP) then my form's OnClose event gets called.

why don't use the OnCloseQuery event?
It's called when message WMQueryEndSession is received by the form...
and there you can also reject the closure setting canclose to false
