How can I change the style of a progressbar in WPF? On Windows 10 it's a straight bar, but in win 7 it's splitted in many small blocks. I want to have the bar straight as on win 10, when the application is used on win 7

                    NOTE: There's a library called MahApps.Metro that styles all the controls to be the more modern metro theme. You might want to look into that. Source code is available on GitHub. – Berin Loritsch Mar 29 '17 at 12:28

I just lookng for a property like 'ugly-block-spacing' which I can set. Or do I have really define the whole style new?
Yes, I am afraid you will have to re-define the entire ControlTemplate from scratch. You cannot override only a part of a ControlTemplate: 
WPF: Is there a way to override part of a ControlTemplate without redefining the whole style?
But you could copy the default ControlTemplate by right-clicking on a ProgressBar in design mode in Visual Studio on a Windows 10 computer, edit it as per your requirements and then use style i your application instead of the default one.
Progressbar has a property called Style, you could set it to your liking.

If you give Metro a try, you could use somthing like this:
<metro:MetroProgressBar x:Name="pbar" Value="50" Height="20"></metro:MetroProgressBar>
If you want to use the normal bar with Metro Style:
<ProgressBar x:Name="pbar" Value="50" Height="20" Style="{StaticResource MetroProgressBar}"></ProgressBar>
Same without Style:
<ProgressBar x:Name="pbar" Value="60" Height="20" Style="{x:Null}"></ProgressBar>
