The font is a property of the console. If you start TCC from a shortcut, right click the shortcut and look at its properties. Also, with REGEDIT, look in HKEY_CURRENT_USER\Console\... You may find at least one subkey named (roughly) for TCC. In it will be various console properties. If you don't have a shortcut and don't find such a registry key then TCC will be using the default console properties, which are in HKCU\Console itself.
