WDF_VIOLATION BSOD on Windows 10 / ProDesk 400 G3 SFF

[Philcp]

I can't find the SRT or WD folder on my PC, so am still looking/waiting for solution, really don't want to to reinstall!

[ChalkTeam]

So I've just tried this and:

rename c:\windows\system32\drivers\wd\wdfilter.sys wdfilter.old.sys

Resolved the issue on a ProDesk 400 G4!

Thank you that help!

Renaming HpqKbFiltr.sys and wdfilter.sys. fixed all of our PCs.

The reason I couldn't find the hpqkbfiltr.sys file is because in recovery mode Windows defaults to drive letter X:\ which is a virtual drive. You have to get to the actual drive where windows is stored in my case drive E: and then all works fine.

For the uninitiated like myself this means when you go into command prompt you see X:\Windows\System32>

Now type cd E: (or whatever you drive letter is) and then cd E:\windows\system32\drivers>ren hpqkbfiltr.sys hpkbfiltr.sys.old

Taken me a long time to get there.

found out that

Windows update HP Development Company LP System 11/19/17 12:00 AM 7.0.1.1

is the problem (we had it with Elite Desk 800G3 systems)

solution:

in the command console go to C:\Windows\System32\drivers

and rename the fille "HpqKbFiltr.sys"

reboot and everything is fine.

It would be good to know how to prevent this update in advanced.... here is just the solution when it's to late...

Thank you so much RService, you've saved me a dozen or so rebuilds! 🙂
