Because unlike the whole Win9x/ME family, Windows 2000 is a fully protected operating system, so it simply can't let any arbitrary program access arbitrary memory addresses, just like that. In NT, and thus in 2000, too, only kernel mode drivers have (almost) full access to all of the system. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
