I have an issue with sfc /scannow. It finishes the verification process and informs me of errors there were unable to be fixed. I looked into CBS.log file and I found four entries related to drupdate.dll. As I understand, this is related with driver updates over windows update? I'm running Win 10 Pro x64.

AMD A6 5200



This is a snippet of that error

I tried using dism /checkhealth (not the precise command, I don't know it from my head). What else can I do?

I tried asking MS support but they give me useless advice. The reason I used sfc /scannow is because KB3140768 Cumulative update fails to install. Also I tried manually replacing the drupdate.dlls that I have found and they were 1kb in size. I replaced them with the ones from the ISO image of Win 10 and still the same error occurs in sfc.


Download the Update KB3139907, use 7zip to extract the MSU. Now use expand.exe to extract the KB3139907.CAB:

expand -F:* C:\Windows10.0-KB3139907-x64.cab C:\Windows10.0-KB3139907-x64

Now run Dism /Online /Cleanup-Image /RestoreHealth /Source:C:\Windows10.0-KB3139907-x64 /LimitAccess to restore the Dll.
