HLK test for volume lowerfilter driver


I have a filter driver as LowerFilter of the “volume” class.
What is necessary to make it visible in the hlk studio?
I need to get this singed by MS for W10 1709.

Extracts from the .inf file:

Class = Volume
ClassGUID = {71A27CDD-812A-11D0-BEC7-08002BE2092F}
HKLM, System\CurrentControlSet\Control\Class{71A27CDD-812A-11D0-BEC7-08002BE2092F}, LowerFilters, 0x00010008, “mydriver”

I searched other threads here and tried to use device manager (show hidden devices),
also tried the devcon - but what is the hwid I should use? … all with no success.

Which selection from HLK should show the driver? (Device/DeviceManger/Software Device)

FYI: I was able to run through all this with my fs minifilter and got it signed by MS.


I was able to select “mydriver.sys” under “device manager/volume”.
No idea why it’s shown now and not earlier - I did several installs and reboots.
