This is quite clearly a breach of copyright.The logo will have been based on a sketch made by or for Microsoft, and so protected by copyright, and so cannot be used without a licence from the copyright holder. I would strongly recommend withdrawing this one. I also strongly suspect the "Vista Sound Effects" item released at about the same time is in the same boat, being a breach of sound recording or other copyrights.
