Hello all,

I my design, I need a volume upper filter driver. I do not know hot to write a volume upper filter driver INF file which used to install the volume upper filter driver. From DDK, I got that in the [Version] field, I need to fill ‘Class’ and ‘ClassGUID’. I try to fill ‘Class’ as volume and ‘ClassGUID’ as {71a27cdd-812a-11d0-bec7-08002be2092f}. But when I install the driver using this INF file. System tell me that can not fine any hardware description infomation.

So, how to fill ‘Class’ and ‘ClassGUID’ field in INF file for a volume upper filter driver? How can I find a sample?

WinDDK\6000\src\storage\filters\diskperf\

Class = DiskDrive
ClassGUID = {4d36e967-e325-11ce-bfc1-08002be10318}

You can install driver using CreateService.
After CreateService, write registry
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{71A27CDD-812A-11D0-BEC7-08002BE2092F}”,
Add your driver’s name in “UpperFilters”

This method can be used for install DiskDrive filter driver, I think
it also can be used here.

It maybe need reboot.

Use INF files to install filters under/over Microsoft drivers if you want your drivers to run on x64 Windows too. You would wish to sign these INFs/binaries.

I think that INF is not a must, since x64 signature can be embedded to the
binary.

The embedded signature can be signed using your company’s certificates.
The WHQL’s signature is not necessary.
Just sign the sys file. You does’t need generate a catalog file and sign the
catalog file.
