The following Registry path is for entries describing the fonts used for character-based programs:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
\GRE_Initialize
The FONTS.FON and FIXEDFON.FON entries do not affect the console, but they do affect menus and dialog boxes and some applications such as Notepad.
Caution Editing these entries can cause menus and dialog boxes to display improperly.
Unlike versions of Windows from MSD, changing these default fonts will render poor results, because the font set under Windows NT is closely tied to the driver.
FONTS.FON REG_SZ Filename
Specifies the filename of the default system font.
FIXEDFON.FON REG_SZ Filename
Specifies the filename of the default system fixed-width font.
OEMFONT.FON REG_SZ Filename
Specifies the filename of the default OEM (or console) font.
