 <ContentControl.Content>
            <Button Name="btnUpdateCommand" HorizontalAlignment="Right" Grid.Row="2" Command="{Binding UpdateCommand}" Height="23" Margin="0,4">
                <StackPanel Orientation="Horizontal" Name="txtUpdate" HorizontalAlignment="Right">
                    <TextBlock Text="{Binding InstallButtonText}"  DockPanel.Dock="Right" Margin="5,2,0,0" HorizontalAlignment="Right"></TextBlock>
                    <TextBlock Text="{Binding FormCloseCountDown}"  DockPanel.Dock="Right" Margin="5,2,0,0"></TextBlock>
                </StackPanel>
            </Button>
        </ContentControl.Content>

You're explicitly setting the Width of the Button (to 175). Remove this attribute; this will allow the Button to determine its own optimal width.

While you're at it, remove the DockPanel.Dock attributes on the TextBlocks; these attributes do nothing since the TextBlocks are inside a StackPanel, not a DockPanel.
