I just sent directions to a colleague on the work pipeline that we are using on windows 7. We have a hidden SSID that we use for prototyping so the steps are a little different. I thought I would share this rough outline with the larger community in case its useful to anyone else!
----------------------------------------
First - Make sure your galileo is connected to the internet:

A) generate the wpa-supplicant file (using arduino example or using step 1 in Sergi's tuturial above)
B) Modify the wpa-supplicant to have "scan_ssid=1" after the psk using vi
C) add "auto wlan0" (see step 3) to the /etc/network/interfaces file so it works every time you restart
D) use ifup wlan0 to restart the network lease process a few times if doesn't work.
E) TEST! ping google.com and see if that works.
--------------------------------------------
Second -Now you are ready to setup SFTP for rapid Prototyping on Intel Galileo once you are connected to a Wifi Netork.
Configure galileo to allow SFTP (using OpenSSH)
https://communities.intel.com/thread/46175
in etc/ssh/sshd_config
change the Subsystem line to this: "Subsystem sftp internal-sftp"
---------------------------------------------------------------------
Finally, choose an environment: Sublime or FileZilla
Make sure your computer is on the same network as the Galileo.
Using Filezilla:
Host name/IP Address (get this by calling ifconfig from the linux side of galileo over the serial port)
Choose SFTP as your communication protocol
Using Sublime:
1) install package manager (put script in)
2) CNTR-SHIFT-P (brings up commandline browser) type: "install"
3) Select "browse packages": Install Package (press enter)
4) Search for SFTP (hit enter)
5) SFTP is now installed
6) CNTR-SHIFT-P - add a new server root@192.168.15.xxx /home/root (or whatever directory you want it to start at)
As long as your computer is on the same network as the galileo, you should be able to browse the galileo file system from your editor, modify files and save them and test from putty immediately.
