It does not seem to be possible to set Fixedsys as the Console font for the Windows 7 command prompt. Setting it in the Registry silently fails and it does not appear in the Fonts list of the console. This might be due to several reasons:
Fixedsys is the oldest Windows font. It might not support all the current criteria of a console font.
Fixedsys is a progenitor of the font Lucida Console, which already appears as an option in the console.
Fixedsys is a raster font (also called bitmap font) and the only raster fonts supported for the Windows Console are already listed in the Console.
There is no font file named
fixedsys.*. Fixedsys is a font name mapped to several old raster fonts with the name pattern
*fix*.fon found in the
C:\Windows\Fonts directory. These fonts are aimed at different old terminals like VGA, CVGA and others. On Windows 7, these fonts are:
8514fix.fon 8514fixe.fon 8514fixg.fon 8514fixr.fon 8514fixt.fon c8514fix.fon cvgafix.fon h8514fix.fon hvgafix.fon j8514fix.fon jvgafix.fon s8514fix.fon svgafix.fon vgafix.fon vgafixe.fon vgafixg.fon vgafixr.fon vgafixt.fon
If you really want Fixedsys as a console font, get a Fixedsys clone that is available as a TrueType Font (TTF). One such clone is FixedsysTTF which can be used on the console. Set it to size 16 and Bold and it looks exactly like Fixedsys does by default.
