Hi there
I decide to make nice desktop icon using NA logo. Fell free and follow those instructions: copy file from this link and save it on your pc: http://i.imgur.com/1zxxTMd.png
Open this link after: http://convertico.com/and drag downloaded file into box, convert to extension .ico and save it on your pc.
Next click RMB on NA desktop icon (if you have one on desktop) and choose properties/change icon, browse and choose saved .ico file and enjoy!
