@refack No, it is not, at least not in the top-level environment. %COMSPEC% must always be a valid path to an executable acting as the "shell". However, the value of %COMSPEC% can be modified by users and can be overriden and/or deleted for child processes. Windows will not prevent that, even though it is not intended behavior.

The same way a user can remove cmd.exe from the Path or from the system completely.
IMHO we should deprecate the || 'cmd.exe' part.
