Everyday, an increasing number of applications are available on the Windows Store. That means that an increasing number of people are using the Segoe UI font. And I’ve got often that kind of question, in the meetings I organize : “Now that I’ve done my Windows 8 application, I would like to use the Segoe UI font as my compagny main font. Can I use it freely?”

Of course, this font, like every material available in the Microsoft eco-system is copyrighted. It required some legal stuff to be properly done to acquire the right to use these fonts !

You can first find legal informations here :
