*Windows Server 2008 server core installation not affected. The vulnerabilities addressed by these updates do not affect supported editions of Windows Server 2008 if Windows Server 2008 was installed using the Server Core installation option, even though files affected by these vulnerabilities may be present on the system. However, users with the affected files will still be offered this update because the update files are newer (with higher version numbers) than the files that are currently on your system. For more information on this installation option, see Server Core. Note that the Server Core installation option does not apply to certain editions of Windows Server 2008; see Compare Server Core Installation Options.
