Microsoft update to revoke 9 "private" UEFI modules that could be loaded during SecureBoot

Microsoft is announcing the availability of an update for Windows 8 and Windows Server 2012 that revokes the digital signatures for nine private, third-party UEFI (Unified Extensible Firmware Interface) modules that could be loaded during UEFI Secure Boot. When the update is applied, the affected UEFI modules will no longer be trusted and will no longer load on systems where UEFI Secure Boot is enabled.
