Known issues with this security update

• You receive a STOP 0x6B error message when you restart a computer after you perform a specific System Restore operation. For example, the issue might occur in the following scenario:
  • You install this security update. During the installation, a restore point is automatically created.
  • You perform a System Restore operation to restore the system to the restore point that was created by this security update.
  • The computer is restarted. Notice that the system is now in an unprotected state because the security update was removed.
  • You try to undo the System Restore operation.
  • The computer is restarted, and then you receive the STOP 0x6B error message.
  To resolve this issue, you can use the Startup Repair recovery tool. For more information, go to the following Microsoft webpage:

• When the system is restarted to complete the installation of this security update, you receive a STOP 0x6B error message. This problem may occur if either of the following registry entries is missing:
  
  
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners\amd64_microsoft-windows-ntdll_31bf3856ad364e35_none_13be95395ddc6d7a
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Winners\wow64_microsoft-windows-ntdll_31bf3856ad364e35_none_1e133f8b923d2f75
  
  The missing registry entries could be caused by corruption in the registry or elsewhere in the system. Be aware that the corruption would have existed before the security update was installed. The corruption is not caused by the security update.
  
  
  
  Note As a mitigation for this issue, this security update will not be automatically offered to systems that do not have these registry entries. We are still looking for evidence to determine whether this is a widely applicable issue when the registry entries are missing.
