You receive a 0x800f0922 error when you try to install this security update
Symptoms Consider the following two configurations:
Configuration 1 You have a Windows Server 2012-based server that uses UEFI firmware and has the Secure Boot option enabled.
Configuration 2 You have a Windows Server 2012 R2-based Hyper-V host running and 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 2962824may not install, and you receive a 0x800f0922 error message.
Cause This error occurs because the installer for security update 2962824 incorrectly expects BitLocker to be installed.
Workaround To work around this issue, use one of the following methods, based on your scenario:
Workaround for configuration 1 Install the BitLocker optional component on the server that uses UEFI and that has the Secure Boot option enabled.
Workaround for configuration 2 Generation 2 virtual machines are not affected by this issue, and you do not have to install the update in this case.
Note You do not have to configure BitLocker on any drive. It is necessary only for the BitLocker component to be present on Window Server 2012 when you install security update 2962824.
