I found the solution that clear the window from the memory:
A,B and C is Window. I open them from the main mxml.
When you close the a , b or c, you would set the a, b or c null in the main mxml.

private var a:A = null;
private var b:B = null;
private var c:C = null;

private function showWindow():void {
a = new A();
b = new B();
c = new C();
a.addEventListener(Event.CLOSE, function(e)

{ a = null; System.gc(); }

);
b.addEventListener(Event.CLOSE, function(e)

{ b = null; System.gc(); }

);
c.addEventListener(Event.CLOSE, function(e)

{ c = null; System.gc(); }

);
a.open();
b.open();
c.open(true);

}
