More Information

Known issues with this security update

  • You cannot start the computer after you install this security update



    If you install this security update on a system that uses a noncompliant Unified Extensible Firmware Interface (UEFI) module, you may be unable to start the computer.

    If your system will not start after you install this security update, follow these steps:

    1. Use Windows Defender Offline to make sure that no malware is present on the system. For more information, go to the following Microsoft webpage:

      http://windows.microsoft.com/en-US/windows/what-is-windows-defender-offline

    2. Restart the computer by using recovery media (on USB, DVD, or network (PXE) boot), and then perform recovery operations. For more information, go to the following Microsoft webpage:

      http://technet.microsoft.com/en-us/library/hh824874.aspx

    To avoid this issue, we recommend that you apply this update after you remove noncompliant UEFI modules from your system to make sure that the system can successfully start, and consider upgrading to compliant UEFI modules if they are available.

    For more information about your UEFI module, contact the UEFI module supplier. This might include the system vendor, the plug-in card vendor, or other UEFI software vendors such as UEFI backup and restore solutions, UEFI anti-malware, and so on.

    For information about how to contact the UEFI module supplier, visit the following Microsoft website:

  • You receive a 0x800f0922 error when you try to install this security update

    Symptoms
    Consider the following two configurations:

    • Scenario one
      You have a Windows Server 2012-based server that uses UEFI firmware and has the Secure Boot option enabled.

    • Scenario two
      You have a Windows Server 2012 R2-based Hyper-V host running and you are running a Generation 2 virtual machine guest that uses UEFI firmware support and has the Secure Boot option enabled. The guest virtual machine is running Windows 8 or Windows Server 2012.

    In these configurations, security update 2871690 may not install, and you receive a 0x800f0922 error message.

    Cause
    This error occurs because the installer for security update 2871690 incorrectly expects BitLocker to be installed.


    Workaround
    To work around this issue, use one of the following methods, based on your scenario:

    • Workaround for scenario one
      Install the BitLocker optional component on the server that uses UEFI and that has the Secure Boot option enabled.

    • Workaround for scenario two
      Install the BitLocker optional component on the guest virtual machine in the Hyper-V configuration.

    Note You do not have to configure BitLocker on any drive. It is only necessary for the BitLocker component to be present on Window Server 2012 when you install security update 2871690.
