don't rely on cmd.exe because in future versions of windows that will be removed for powershell. Not unless you expect them to rip cmd.exe from Windows 7.

[retep998]

cmd.exe has not been removed from Windows yet, not even in insider builds. Microsoft has merely hidden it from certain places to make powershell more of a default option. We can reevaluate the decision to use cmd.exe if Microsoft ever does take such a drastic step, but at the moment cmd.exe is a significantly better choice than the status quo of using gnu utilities that don't exist on Windows in the first place.

@AraHaan To dissuade your fears, Microsoft has even published a blog post saying that they will not be removing cmd.exe in the near or distant future. https://blogs.msdn.microsoft.com/commandline/2017/01/04/rumors-of-cmds-death-have-been-greatly-exaggerated/
