KMDF filter driver not loading in safe boot mode
Posted by Olivier Lechenne on January 28th, 2008


We have several filter drivers using KMDF, and we noticed that under Windows
XP SP2 they fail to load when you boot in safe mode. Seems that wdf01000.sys
is not loaded in safe mode, causing the filter driver to not load. Issue is
not present in Vista.

Was able to fix this issue by adding the following registry key:
HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Min imal\WdfLoadGroup

Is this a known issue? Was not able to find any information on Microsoft,
but seems that some other people had the same issue.

Thanks for any help,

Olivier

be in the server 2008 wdk

Ok, thanks for the reply!
So the registry keys are the proper way to make this work for previous WDF
releases.
