The reason why Windows 7 doesn't enable full screen mode for the command
prompt has to do with the video drivers. In order to enable true full screen
mode you would need to install Windows XP drivers i.e. XDDM instead of
Windows 7's WDDM video drivers as WDDM doesn't do a type of interrupt.
If you swap out the WDDM video drivers for XDDM, you will lose the Aero
effect.
Anyway, here's Microsoft's answer:

full-screen mode in Windows Vista and in Windows 7 - Microsoft]

As well, the following site discusses 3 workarounds, including a discussion
of video card drivers:

You might consider running XP if the computer is to do single duty employing
the full screen command prompt - I've tried this and it works
