Vista - Oem Up date disable

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.

When the update is installed, no functionality of your operating system will be affected. If no exploits are detected, the update silently exits. If exploits are detected, you will be provided a link to a Web site that describes how you can remove the exploits. When the exploits are removed, you may be asked to use a valid product key to activate your copy of Windows. If you do not want to remove the exploits, Windows may disable the exploits and then ask you to use a valid product key to activate Windows.
