Nothing, probably.

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.
