I've used emacs for years, and on a Windows system. I downloaded emacs from http://ftp.gnu.org/gnu/emacs/windows/ and unzipped it locally.
I copied my .emacs file into %USERPROFILE%\.emacs
and started emacs.
My .emacs file was not loading. I added
(debug)
As the first line of the .emacs.el
file and the emacs debugger did not start so I know the file was not loaded.
I searched for other questions like this but didn't find this question asked.
