SYMPTOMS
When you try to use filter drivers or mini-port drivers in the Microsoft Windows Preinstallation Environment (Windows PE), the drivers do not work correctly.



CAUSE
This issue occurs because Windows PE supports the use of only monolithic drivers.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
A monolithic driver is a type of device driver that contains all the instructions that are required for the system to function without being required to communicate with the miniport driver subsystem.

Windows PE is a minimal Win32 subsystem that is based on the Microsoft Windows XP Professional kernel when this kernel is running in protected mode. Windows PE contains the minimal functionality that you must have to perform the following operations:
 * Run Windows Setup.
 * Install an operating system from a network share.
 * Automate basic processes.
 * Run hardware validation.
