This is a FYI and not an ask for help.

On my Windows 10 installation I have done a registry hack to change the default font (menus, icons...).

I bought the upgrade offer "pack" with Boris, New Blue and ProDAD. I was on 12 Pro.

I observed that one of the "addon"-installers (Boris, New Blue and ProDAD) changed the registry back to default 'Segoe UI' (what Microsoft want you to have).

Not difficult to change back. But the annoyance factor is very high.
