This is very strange. Do you have `bash' installed on your system?

Anyways, Emacs defaults to cmd.exe on Windows. Do you have any package
that brings in Unix-like commands? Examples are Gnuwin32, MSYS, MSYS2,
MSYSGit, Cygwin...

As far as Emacs is concerned, you only need c:\Emacs\bin in your PATH.
And you don't really need that if you always execute runemacs.exe with a
fully qualified pathname (c:\Emacs\bin\runemacs.exe in your case) as
usually is done when usin a Windows shortcut.

However, there is much missing on your PATH. It lacks the Windows system
directories. So you either are not showing the full contents of PATH or
you overwrote it with the Emacs directories instead of
appending/prepending them, which is the correct practice.

I suspect that you have one of the Unix-like packages mentioned above,
that the directory where those Unix-like binaries are installed on was
previously listed on your PATH (or they were on the same directory were
you installed Emacs the first time) and that you thought that you were
running `bash' when in reality you were running the `ls.exe', `cp.exe`,
etc binaries of the Unix-like package.

BTW, it is possible to use `bash' as the Emacs shell on Windows. It has
some caveats, though. There are several places on the Web that explain
it.
