Download emacs-24.5-bin-i686-mingw32.zip from GNU and extract it.

Run it using a minimal path to avoid crashes when closing:

set path=C:\Users\kevin.cantu\Desktop\emacs\emacs-24.5-bin-i686-mingw32\bin

Download gnutls-3.4.9-w32.zip from GnuTLS and exctract it.

Test it against a website:

set path=C:\Users\kevin.cantu\Desktop\emacs\gnutls-3.4.9-w32\bin
gnutls-cli -p 443 elpa.gnu.org

To trust ELPA, we can install the Let’s Encrypt Authority X3 certificate (fingerprint: e6:a3:b4:5b:06:2d:50:9b:33:82:28:2d:19:6e:fe:97:d5:95:6c:cb) on the system. For example, open Internet Options -> Content -> Certificates -> Intermediate Certificate Authorities, and install it there.

Then we can see GnuTLS trust that like so:

C:\code\infr>set path=C:\Users\kevin.cantu\Desktop\emacs\gnutls-3.4.9-w32\bin

C:\code\infr>gnutls-cli -p 443 elpa.gnu.org

I think maybe that should make the --insecure flag unnecessary, but YMMV...

Now I'm trying to get GnuTLS working from inside Emacs. By default, it's missing:

set path=C:\Users\kevin.cantu\Desktop\emacs\emacs-24.5-bin-i686-mingw32\bin
set path=%path%;C:\Users\kevin.cantu\Desktop\emacs\gnutls-3.4.9-w32\bin
runemacs

Using the elisp eval, M-: (ESC-SHIFT-;):

(gnutls-available-p)
nil

And copying the folders over isn't enough, either...

However, downloading the out-of-date gnutls-3.3.11-w32-bin.zip from ezwinports and exctracting into the emacs folder works!

(gnutls-available-p)
t

Now, using the gnutls-3.3.13-w32.zip from GnuTLS, it works the same.

To get Git working, though, I've set up a script with more on the path:

C:\Program Files (x86)\emacs>cat runemacs.bat
@setlocal enableextensions enabledelayedexpansion
@echo off

echo Launching Kevin's Emacs

set path=%~dp0\emacs-24.5-bin-i686-mingw32\bin

set path=%path%;%LocalAppData%\Programs\Git\cmd
set path=%path%;%LocalAppData%\Programs\Git\bin
set path=%path%;%LocalAppData%\Programs\Git\mingw64\bin
set path=%path%;%LocalAppData%\Programs\Git\usr\bin
