This is a kpathsea variable and explained in the docs.  Try

  kpsewhich --var-value=SELFAUTOLOC
  kpsewhich --var-value=SELFAUTODIR
  kpsewhich --var-value=SELFAUTOPARENT

They are all relative to the location of the binaries.

It doesn't matter what Windows believes, all which matters is that

  kpsewhich texmf.cnf

finds the correct file.

BTW, you can also use Emacs as a file manager.  It always shows the
extensions.  I've put one for Windows on CTAN:

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
