Do you have the sub-shell customized to invoke a Unixy shell or
something? Windows shells don't support quoting 'like this', so you
need to use "*.log" instead. And, depending on which port of GNU
Findutils you have installed, even "*.log" could get expanded, even
though it's quoted, because Windows Vista changed its interpretation
of quoting wrt previous versions of Windows.
Also, I wonder how come Emacs doesn't propose to the the command with
"+" as it did for me.
FWIW, your command (with a different search string) works for me, but
it isn't surprising, since in your case it sometimes works and
sometimes doesn't.
GNU Emacs 24.5.1 (i686-pc-mingw32)
Emacs 24 is quite old. Could you try the latest pretest of Emacs 26,
please?
