Garbage in font name from uninit struct on stack?
Before call bzero/memset/implicit:

-  CONSOLE_FONT_INFOEX cfi;
+  CONSOLE_FONT_INFOEX cfi = { 0 };

and remove loop, which opens an attack vector by renaming a good font and
substituting one with a shorter name, or could cause problems by using the wrong
font e.g DejaVu Sans.

You need to self-impose a change freeze before heading out, once you're in
"stuff to get done before leaving" mode, which may be a day or up to a week, you
delegate or postpone decisions and actions until you return: BTDTGTS (Got The
