Creo que voy a responder mi duda yo mismo...

Encontre esto:

Código Delphi [-]
unit Unit1;  

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

type   TForm1 = class(TForm)   

private   
protected     
  procedure CreateParams(var Params: TCreateParams); override;   
public   
end;  

var   Form1: TForm1;  

implementation  

{$R *.dfm}  

procedure TForm1.CreateParams(var Params: TCreateParams); 
begin   

inherited;   
Params.ExStyle := Params.ExStyle or WS_EX_APPWINDOW;   
Params.WndParent := GetDesktopWindow; 
end;  
end.
