Does Windows Emacs need other installs to provide Unix commands?

[gnu . panda989]

Hi,

I downloaded GNU Emacs for Windows from here:

https://www.gnu.org/software/emacs/download.html#nonfree

Some of my favorite dired​ commands do not work. The errors mention commands that Emacs would find in the system if it were running on, say, Linux (eg: find, xargs, ls). For example, I can't mark files and search for a string (`dired-do-find-regexp`). I can't run find-name-dired​. To get past that, I set the variable find-program​ to point to a binary that came with Git, but then it fails again because there is no ls​. 

Am I supposed to also install Cygwin or something like that, to provide these Unix commands to Emacs? It seems strange to me that there was no mention of this on the download page. Maybe it's just a few dired commands and I notice because I like to use them.
