It is a spoofed number that belongs to Christine Hall.  She probably doesn't know some criminals in India are using it to con foolish people into believing they are with Microsoft and that they need to give the criminal remote access to their computer.  It is, unfortunately, far too easy for criminals to make your caller ID display whatever they want it to display.  Stop even bothering with bitching about the do-not-call list.  Criminals don't care.
