Blocking Untrusted Fonts
Blocking untrusted fonts is sometimes a good idea for a company to keep their system safe. However, this can also cause some usability issues for some users. It is a global setting that prevents all programs from loading untrusted fonts. Internet Explorer will face the issues regarding this setting, but other browsers will be fine. The untrusted fonts are those that are installed outside of the default fonts folder (%windir%\Fonts). There are three modes in this feature and that is On, Off, and Audit. By default, this setting will be “Off” and no fonts are blocked. Setting it on “On” will completely block the untrusted fonts. Also, if you are not sure to deploy this feature into your company completely, then you can run it in the “Audit” mode to see if turning this on causes any usability or compatibility issues. You can also install fonts manually in the default font folder while this setting is enabled.
