cmd.exe is just a shell that uses the console (if the standard handles
are console handles). The console window is hosted by conhost.exe. It
processes the input buffer for command-line editing, and it maintains
command history and a set of aliases (matching at the start of a line)
for each attached executable (e.g. cmd.exe, powershell.exe, chcp.com,
mode.com, doskey.exe, python.exe, etc). Every Windows process can
attach to a single console window via AllocConsole or AttachConsole,
and detach via FreeConsole.
