Come connettere Themes/Generic.xaml a window1.xaml?

Question

Ho il seguente stile di pulsante in Temi/Generic.xaml e voglio che si applichi ai pulsanti ovunque nella mia applicazione WPF.

Come collegarlo a window1.xaml, ad esempio?

<Style TargetType="{x:Type Button}"> 
    <Setter Property="SnapsToDevicePixels" Value="true"/> 
    <Setter Property="OverridesDefaultStyle" Value="true"/> 
    <Setter Property="MinHeight" Value="23"/> 
    <Setter Property="MinWidth" Value="75"/> 
    <Setter Property="Template"> 
    <Setter.Value> 
     <ControlTemplate TargetType="{x:Type Button}"> 
     <Border 
      x:Name="Border" 
      CornerRadius="2" 
      BorderThickness="1" 
      Background="#C0C0C0" 
      BorderBrush="#404040"> 
      <ContentPresenter 
      Margin="2" 
      HorizontalAlignment="Center" 
      VerticalAlignment="Center" 
      RecognizesAccessKey="True"/> 
     </Border> 
     <ControlTemplate.Triggers> 
      <Trigger Property="IsKeyboardFocused" Value="true"> 
      <Setter TargetName="Border" Property="BorderBrush" Value="#202020" /> 
      </Trigger> 
      <Trigger Property="IsDefaulted" Value="true"> 
      <Setter TargetName="Border" Property="BorderBrush" Value="#202020" /> 
      </Trigger> 
      <Trigger Property="IsMouseOver" Value="true"> 
      <Setter TargetName="Border" Property="Background" Value="#808080" /> 
      </Trigger> 
      <Trigger Property="IsPressed" Value="true"> 
      <Setter TargetName="Border" Property="Background" Value="#E0E0E0" /> 
      <Setter TargetName="Border" Property="BorderBrush" Value="#606060" /> 
      </Trigger> 
      <Trigger Property="IsEnabled" Value="false"> 
      <Setter TargetName="Border" Property="Background" Value="#EEEEEE" /> 
      <Setter TargetName="Border" Property="BorderBrush" Value="#AAAAAA" /> 
      <Setter Property="Foreground" Value="#888888"/> 
      </Trigger> 
     </ControlTemplate.Triggers> 
     </ControlTemplate> 
    </Setter.Value> 
    </Setter> 
</Style>
