Not all items have a Font selection.
NOTE: Not all options for all Window elements are available. For example,
the Font option appears dimmed and is unavailable for elements in the Item
list that do not display text.
NOTE: You can change the look of individual items if you select Windows
Classic style in the Windows and buttons list on the Appearance tab of
Display Properties.
Right-click an empty area of your desktop, then click Properties, and then
click the Appearance tab. Under Windows and buttons, change to Windows
Classic style and click Apply.
If you select a visual style other than Windows Classic, that style
determines the appearance of your menus, fonts, icons, and other Window
elements.

If you select a Windows and buttons setting other than Windows Classic, it
will override the following settings, except in some older programs.
Note: In order to fully use this feature you must have your Windows and
buttons setting on Windows Classic.
