# How to: Get all Windows in an Application
This example shows how to get all <xref:System.Windows.Window> objects in an application.
## Example
Every instantiated <xref:System.Windows.Window> object, whether visible or not, is automatically added to a collection of window references that is managed by <xref:System.Windows.Application>, and exposed from <xref:System.Windows.Application.Windows%2A>.
You can enumerate <xref:System.Windows.Application.Windows%2A> to get all instantiated windows using the following code:
[!code-csharp[HOWTOWindowManagementSnippets#GetAllWindows](~/samples/snippets/csharp/VS_Snippets_Wpf/HOWTOWindowManagementSnippets/CSharp/CustomWindow.xaml.cs#getallwindows)]
[!code-vb[HOWTOWindowManagementSnippets#GetAllWindows](~/samples/snippets/visualbasic/VS_Snippets_Wpf/HOWTOWindowManagementSnippets/visualbasic/customwindow.xaml.vb#getallwindows)]
