I have read the entries for other OS versions.
- Changing the MS Shell Dlg (2) entries in FontSubstitues registry keydoesn't seem to work (in Windows 10), or it works in two minorplaces.
- I don't have access to a Windows 95/98/etc. machine, the"earliest" I have is Windows 8.1, so I can't use the Plus directorytrick either (directory doesn't exist).
- For the WindowMetrics registry entry, I seem to have all the *Font keys to be set to the font I want, but that doesn't seem to be doing the trick (on Windows 10).
- For Windows 8/8.1, there was a program called
Windows 8 Font Changer, which worked like a charm, but doesn't seem to on Windows 10 (though it was probably that program run that changed the fonts in the WindowMetrics).
Update: One more method that came out that is perhaps still not the solution: Winaero Tweaker (winaero.com), as it has some issues, the biggest two of which seem to be:
If you have changed the size of text etc. from: "Settings –> Display –> Advanced display settings –> Advanced sizing of text and other items –> set a custom scaling level (not recommended)", the changes do not stick upon a logoff-login or restart. You need to have changed it, if at all, only through "Settings –> Display –> Change the size of text, etc." (which goes up to only a certain percentage, depending on the maximum resolution of your device – 125% on a tablet of mine, which I was able to set to 175% or even 200% with the other, older method that is now apparently listed as not recommended).
Even though it lists a number of items to change the font and size of, not everything gets changed. A typical example of this is the right click menu on the desktop, which still shows the View, Sort By, etc. items in the default font, however much it has a clear 'Change menu font' item.
