Brand new, completely genuine, factory sealed, retail package for Windows XP Professional with Service Pack 2.   Full copy, not an upgrade version - for PCs with Windows 95 or earlier or PCs without Windows.  Has been sitting at the back of a cupboard for quite a while - box is a little bit dented and has a sticker on the front where I bought it, but otherwise as new.  E85-02665 / X10-87160.
