In Windows, there is the "Window Color and Appearance" dialog. There you can change: title, message box, menu, status bar,icon fonts... However you cannot change the default window font.
It is always "Tahoma" 8.25
I can change its face by changing HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes\"MS Shell Dlg 2" value: as a result I have "Tahoma", 14
But it does not change the size. - how can I change 8.25 to something higher, to make the font legible?
Just out of curiosity, is there any plausible reason for Microsoft not allowing to change it?
If I change dpi scaling it will change the rendering size of all fonts without changing the size. It also causes some applications to have controls outside the window boundary.
What I would like to do is to set default windows dialog font to "Segoe UI", 14 (just like I can change messagebox font).
This question was already asked on: answers.microsoft.com but never answered
Also on: superuser.com a kind of similar question was asked, but no usable answer about the font size was given.
Here a screenshot of what font size I would like to change:
