I don't use Windows 8, but I just checked on Windows 7, and it works for me.  I created a ~/.authinfo file with the following contents:

machine smtp.googlemail.com login <my-login> port 587 password <my-passwd>

And I put the following in my ~/.emacs:

(require 'smtpmail)
(setq smtpmail-smtp-server "smtp.googlemail.com")
(setq smtpmail-smtp-service 587)
(setq send-mail-function 'smtpmail-send-it)

[I used "smtp.googlemail.com" because that's the smtp server in my Thunderbird gmail account.]

With these settings I can send mail successfully.  I do get the following in the *Messages* buffer after sending mail:

Sending via mail...
gnutls.c: [1] Note that the security level of the Diffie-Hellman key exchange has been lowered to 256 bits and this may allow decryption of the session data

Sending email 
Sending email done
gnutls.c: [0] (Emacs) fatal error: The TLS connection was non-properly terminated.
Sending...done
