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. If you chose to manually select updates to be installed, you should find this update listed.
You can see that the KB940510 update is listed as Important. At this point, most users would assume it's an important patch that fixes flaws in Windows Vista and install it. Double-click on the update and you will find this short description.
Microsoft describes the KB940510 update as such :
This update enables Windows Vista to detect activation exploits that bypass product activation and that interfere with usual Windows operation. An exploit is a form of software that replaces or modifies authentic Windows components. When exploits are present on a system, it indicates that a software or hardware vendor may have tampered with genuine Windows to enable the sale of counterfeit software. Therefore, the security and the privacy of the computer are put at risk. After this update is installed, you will know if exploits are present on the system.
