Invalid macro definition on shell startup

[Rob Stivers]

Seeing this on cmd.exe startup.
Is there a startup file I'm missing?

From "cmd /?":

If /D was NOT specified on the command line, then when CMD.EXE starts, it
looks for the following REG_SZ/REG_EXPAND_SZ registry variables, and if
either or both are present, they are executed first.

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun

and/or

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
