The "cmd" shell does not do filename expansion; commands that support it
do it themselves--"cmd" is quite minimal. To make that pcompos command
work, it would have to be provided with the full list of files, spelled
out. This could be done in Windows PowerShell or perhaps via some
combination of command. Anyone who knows Windows scripting well willing
to provide an alternative?
