Hi there,
I've got a Windows 8.1 x64 endpoint that will not install Windows Updates.
SFC /SCANNOW
does not find any integrity violations, and
DISM /Online /Cleanup-Image /RestoreHealth
doesn't throw any errors; it completes successfully.
I've been fighting with the following line in
setupapi.dev.log
for about a week now, and I'm growing exhausted. Not sure I can figure it out, as there just isn't anything helpful documented about this online. It's all generic crap that I've already tried. Hoping you folks can lend a hand!
!!! 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"
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!!
PS logs are attached!
Whoops, I should also mention that I've used SFCFix & SFCFixScript to determine what KB corresponds to

Oddly enough, I've already downloaded KB4015547 for x64, and that folder/file isn't there. Very strange.
