[libreplanet-discuss] What can i do with my windows licences

[pascal]

Hi,
i have some windows licences (XP,7,8) paid (by me) or not (with a  
buying computer), and i would to know what do you advise me?
What can we do with this, to send a strong message?
"I have a licence windows with my new (or old) computer. It's too hard  
to be refund, but ... Looks everyone, i don't want this... I choose a  
free OS that respect my freedom for my computing."

Ideas?

Regards.
