Symptoms

Applications are not able to load arbitrary list of DLLs into each user-mode process via AppInit_DLLs mechanism.

Cause

The AppInit_DLLs mechanism is not a recommended approach and can lead to system deadlocks and performance problems.  In order to improve the overall security of Windows 8 and Windows Server 2012, the AppInit_DLLs infrastructure is disabled when secure boot is enabled.

Resolution

Currently, the only resolution is to disable secure boot on the system where an application is attempting to utilize AppInit_DLLs mechanism.
