Вам необходимо настроить стиль Slider. Ниже приведен стиль по умолчанию. Вам просто нужно прокомментировать PointerOver визуальное состояние. Это решение предназначено для приложений Win8. Пусть мне нужно для 8.1 или 8.
<Style TargetType="Slider">
<Setter Property="Background" Value="{StaticResource SliderTrackBackgroundThemeBrush}" />
<Setter Property="BorderBrush" Value="{StaticResource SliderBorderThemeBrush}" />
<Setter Property="BorderThickness" Value="{StaticResource SliderBorderThemeThickness}" />
<Setter Property="Foreground" Value="{StaticResource SliderTrackDecreaseBackgroundThemeBrush}" />
<Setter Property="ManipulationMode" Value="None" />
<Setter Property="Template">

Если вы используете более чем один Slider и хотите удалить PointerOver эффект всего, вам не нужно создавать собственный стиль, но изменять значения в следующем ключе SolidColorBrush в прозрачный или любой соответствующий цвет.
- SliderTrackPointerOverBackgroundThemeBrush
- SliderThumbPointerOverBackgroundThemeBrush
- SliderThumbPointerOverBorderThemeBrush
- SliderTrackDecreasePointerOverBackgroundThemeBrush
например,
<SolidColorBrush x:Key="SliderTrackPointerOverBackgroundThemeBrush" Color="Transparent" />
