Font size - Files, Plot, Packages, Help, Viewer Tabs

Im having a similar problem as :

with the font size on my menu tab, but I use Windows10 ...
I wish I could increase the font size in the Files, Plot, Packages etc.... tabs also!

I can barely read the functions help
How can I change that ?

You can adjust the global zoom, with e.g. View -> Zoom In. This will have the effect of making all UI elements (including text) larger.

Is this sufficient for what you want?
