MUI Fonts

I want to know how I would change the font of a static label with the ID of 4040 to uses the font in the MUI Header "Arial Bold". I have been playing with the macros in System.nsh but i havent figure it out yet.

The Script basicly lets you know what step it is on by making the item bold.

I am sure this isnt but a few lines of code could some on please give me an example.

Thanks in advance,
Nathan

What do you mean? Do you want to change the font of MUI label or another label? And when do you want to change it?
