On my bookshelf lies original, authenticated copy of German Vista Ultimate 64-bit DVD, of course with original key. Itīs been there since summer of 2008, I do not even remember why I bought it. Itīs useless for me, having Vista DVD`s in English and Finnish.
First one to claim can get it free, Iīll even pay the postage.
P.S. Itīs Ultimate, so with language packs anybody can use it, if you just manage installation in German. Non-German speakers I promise help with installation.
