SYMPTOMS
When you are developing an application by using Microsoft Media Foundation Software Development Kit (SDK), the application cannot load the unsigned drivers list the second time or any later time that the application tries to load the list. The first time that the application tries to load the list, the list loads successfully.



CAUSE
This problem occurs because the &quot;Protected Environment Authentication and Authorization Export Driver&quot; reports an unsigned driver only one time.
