The release of Windows Vista Service Pack 1 not only heralded a long-awaited update of the operating system, it also meant the end of two common Windows Vista anti-activation exploits - the Grace Timer exploit and the Paradox OEM BIOS activation crack. But those who think they can escape by not updating to Service Pack 1 would be sadly mistaken.
That's because Microsoft has surreptitiously released an anti-hack detection update via Windows Update. Those who chose to have Windows Vista install updates automatically would have this update installed and running by now.
