You can indeed use your favorite font in OS features like message boxes icons, title bars, etc. Where in earlier versions of Windows 10, you could change the default font using the Control Panel or Personalization settings, now you have to do it manually through the Windows registry. But we’ve also got a way out for you! Windows 10 has definitely made life easier by enhancing user experience but while doing this it has also limited the customizability of the OS.
Are you looking to change the default font in your Windows 10 but seem to be stuck at how you can actually do it? That’s okay.
