Stop windows from showing up as 'tasks' from task manager WPF c#

Question

I have a program that opens multiple windows. I have used this method to hide them from ALT+TAB. Now I need the new windows to stop showing up in the 'tasks' tab of task manager.

I don't need the process not to show up in task manager, I just don't want all the windows my program opens to show up in the 'task' tab.

Here is a picture of what I'm trying to get rid of: http://i1096.photobucket.com/albums/g324/thezaza101/Tasklist.jpg

Another way is to use WindowInteropHelper.

    public MainWindow()
    {
        InitializeComponent();

        SourceInitialized += (s, e) =>
        {
            var win = new WindowInteropHelper(this);
            win.Owner = GetDesktopWindow();
        };
    }

    [DllImport("user32.dll", SetLastError = false)]
    static extern IntPtr GetDesktopWindow();

For WPF the only way I currently know of is to set your window's title to string.Empty or set WindowStyle to ToolWindow. Setting ShowInTaskBar to false does not hide your window from the applications list.
