Hi folks,
The symptoms on this machine are identical to this one:
[SOLVED] - Windows 8.1 will not update - failed to find driver update in driver store
To recap:
SFC /SCANNOW does not find any integrity violations, and
DISM /Online /Cleanup-Image /RestoreHealth doesn't throw any errors; it completes successfully.
!!! sto: Failed to find driver update 'C:\Windows\WinSxS\amd64_wvms_pp.inf_31bf3856ad364e35_6.3.9600.19941_none_53cbf946c53be7dd\wvms_pp.inf' in Driver Store. Error = 0x00000490" is in setupapi.dev.log after updates are attempted.
I confirmed that
C:\Windows\WinSxS\amd64_wvms_pp.inf_31bf3856ad364e35_6.3.9600.19941_none_53cbf946c53be7dd\wvms_pp.inf does exist in Windows. I can open it and it looks fine to me. I've seen these files be gibberish/illegible before, but this one checks out.
There are no missing drivers in the Device Manager, and I've already updated all drivers from Intel's website.
pnputil -a C:\Windows\WinSxS\amd64_wvms_pp.inf_31bf3856ad364e35_6.3.9600.19941_none_53cbf946c53be7dd\wvms_pp.inf throws the following error:
Code:
Processing inf : wvms_pp.inf
Adding the driver package failed : The third-party INF does not contain digital
signature information.
Total attempted: 1
Number successfully imported: 0
Lastly, I've tried disabling driver signature enforcement via
bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS & bcdedit /set testsigning on. Despite the commands executing successfully, they don't change the output of pnputil. That one stubbornly fails consistently. This machine isn't in front of me, so I can't reboot it into the special "Disable driver signature enforcement" advanced start option.
Thank you!!
