Oops. One of Microsoft's big goals in releasing Vista SP1 is the closure of a pair of known Vista activation exploits. While the OEM BIOS hack and grace timer hacks are now indeed useless in the face of SP1, a third remains. Adrian Kingsley-Hughes over at ZDNet tracked down a hack that required "a few seconds in the command prompt" to trick Vista SP1 into thinking it was genuine. Now that SP1 is riding the torrents, we can't say we're surprised.
