 Module Name:

    SuperChix76.cpp

 Abstract:

    Hook LoadLibrary and calls GetDeviceIdentifier which initializes wintrust. 
    
    This fixes the problem whereby the app will hang if they call 
    GetDeviceIdentifier from within a DllMain - which is an app bug.

 Notes:

    This is an app specific shim.

 History:
