You asked for:

> What is the full contents of the environment of the Emacs process when
you run that zapped binary?

My full environment contains a lot of internal information with private
data with security implications

+ current directories
+ current projects
+ complete pathnames to various executables
+ firefox plugins
+ firefox plugin directory paths
+ windows directory paths
+ paths to ssh keys
+ complete specification of the windows image I am running

You do not need my full environment, nor would more than a few people give
it.

And my full environment is not sufficient either.  You need a knowledge of
windows programming.
I cannot supply that. If you cannot, say so.
