I tried following the procedure outlined in this previous answer and it doesn't work: http://superuser.com/a/5079/2366
Specifically I'm trying to add Lucida Sans Typewriter Regular to the choices of Consolas and Lucida Console that the Cmd window currently allows. Lucida Console is in registry key "0" and Consolas is in registry key "00", so I'm adding key "000" but it's not affecting the available choices in the Font tab under Properties, even after rebooting the system.
P.S. I also tried adding Courier New to the choices and it shows up, but appears to select Italic instead.
