Microsoft's Windows Phone Partner Group program lead Reid Kuhn said in a response Monday that his company would desensitize its location tracking system. Following a discovery online that the system had published the locations of phones and notebooks on a public map, Microsoft would no longer guess at the position of a source when only one MAC address (hardware ID) appears in the system. The company had been in direct conversation with the finder, Elie Bursztein, to curb its location checks.
