How to hide windows or open it behind main aplication

I need to open new window behind main screen. This code doesn't work for me. Lets assume I have 2 classes

MainWindow.xaml 

 <Grid>
    <Button Click="ButtonBase_OnClick"></Button>
</Grid>
 private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
       Test t=new Test();
        t.Show();
    }

Test class that I need to open behind Main window 

<Window x:Class="WpfApplication1.Test"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:WpfApplication1"
    mc:Ignorable="d"
    Title="Test" Height="350" Width="525" ShowInTaskbar="False" Visibility="Hidden"   >
<Grid>
    <TextBox/>
</Grid>

I try to use ShowInTaskbar="False" Visibility="Hidden" but it still doesn't work. The problem I can see "Test" windows 1 sec and after it will be unviable(because Visibility="Hidden") .I need to open this windows many times, it will blinks many times. The better solution to open it behind application. Is anyone knows how to do?

The final solution for me 

if (Application.Current.MainWindow != null)
                {
                    Application.Current.MainWindow.Topmost=true;
                }

Try to set the Topmost property of the MainWindow to true:

private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
    Test t = new Test();
    t.Show();

    Topmost = true;
}

This should cause the Test window to be displayed "behind" the main window.
