I try to create style for FocusVisualStyle of the button but it don't work as I expect, this problem also occur when I set IsDefault="True" too.

I know this is an old question, but felt I could answer.
If I understand the problem correctly, after you click the button and move on, a border remains around it. When you click on some other item, like a TextBox or another Button, the border disappears.
This "border" is the "focus" indicator.
To prevent this, set "Focusable" to "False" on the Button:
<Button Background="Transparent" BorderBrush="Transparent" Focusable="False">
<Button.Content>
<StackPanel>
<Image Source="xxx.png" />
<TextBlock Text="Change Password" />
</StackPanel>
</Button.Content>
</Button>

You may have to change the button template, this will give you a button with no frame what so ever, but also without any press or disabled effect:
In your Window.Resources element:
<Style TargetType="Button" x:Key="TransparentButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border Background="Transparent">
<ContentPresenter/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And the button:
<Button Style="{StaticResource TransparentButton}">
<Button.Content>
<StackPanel>
<Image Source="xxx.png" />
<TextBlock Text="Change Password" />
</StackPanel>
</Button.Content>
</Button>
Now, if you need a little more visual feedback start with this template:

and remove things until you get what you want.
Don't forget to add a transparent background to your elements, if you don't have one, or have a null background the transparent area inside teh button will not be clickable.
