Windows 10: sfc /scannow indicates errors after fresh installation and after Windows updates

Sfc /scannow have indicated that there are errors and they are successfully corrected after fresh installation of Windows 10. Yesterday I've done newest Windows updates and this tool indicated errors again. What is the cause? This is my CBS.log.https://drive.google.com/file/d/1t-uPYD1r83YWUd7bF00F6ddvpCQpcyHw/view?usp=sharing

SFC /SCANNOW Errors After Update

I've just updated a Windows 8.1 Pro PC to Windows 10 using the Techbench ISO which updated without any problems. However, I've just run sfc /scannow and it found errors it could not repair. I have managed to get sfc /scannow to run without errors - see what I did below:

1. Ran sfc /scannow which showed error "Windows Resource Protection found corrupt files but was unable to fix some of them."
2. Ran Dism /Online /Cleanup-Image /ScanHealth which reported "The component store is repairable."
3. Ran Dism /Online /Cleanup-Image /RestoreHealth which failed with Error: 0x800f081f "The source files could not be found.Use the "Source" option to specify the location of the files that are required to restore the feature."
4. Mounted the W10 Techbench ISO and ran Dism /Online /Cleanup-Image /RestoreHealth /source:wim:G:\sources\install.wim:1 /limitaccess which reported successfully "The restore operation completed successfully."
5. Ran sfc /scannow wich completed successfully with report "Windows Resource Protection found corrupt files and successfully repaired them."

Please advise:

1. Why would sfc /scannow fail on a newly updated installation which ran sfc /scannow error free immediately before the upgrade?
2. Why did I have to use install.wim from the Techbench ISO at step 4 above for Dism /Online /Cleanup-Image /RestoreHealth to work and will I have to use install.wim from the Techbench ISO every time I need to run this Dism command?
3. How can I configure my PC so it has the correct install.wim file for the Dism command to work properly?

 

SFC /SCANNOW Errors After Update

1. Why would sfc /scannow fail on a newly updated installation ...
   In addition to what essenbe said .... there is a known issue re: opencl.dll - it's been around for a while. If it is opencl.dll (follow SFC Command - Run in Windows 10 - Windows 10 Forums), the error can be ignored.
   
2. Why did I have to use install.wim from the Techbench ISO ...
   I'm not sure, but it seems to indicate that the Component Store cannot be found (resolved). I think this would cripple your system though instead of only showing up in DISM.
   Try the Windows Update Troubleshooter (TS) in Control Panel - then try https://support.microsoft.com/en-us/...troubleshooter (I'm not sure if they are the same, but why would MS offer a diag cab separate from the built-in TS?
   
   Please copy the C:\Windows\Logs\CBS (the entire folder) into a compressed folder on your desktop and attach the zip folder to a post. If it is too large, copy just the CBS.log file into a compressed folder and attach that.
   
3. How can I configure my PC so it has the correct install.wim ...

'SFC /scannow' errors on clean install


I decided to run 'SFC /scannow' on my recent clean install of Windows 10 and was surprised that it reported so many errors that cannot be repaired. I installed on a 256GB Samsung Pro SSD. After trying a few recommended fixes that all failed I decided to do clean install on a second SSD which I just finished doing. The only thing I've done is install Win10 Pro from a USB flash drive, install the motherboard drivers and then let Windows do an update. The update also downloaded and installed the NVidia graphics driver. Then when I ran 'SFC /scannow' the errors were there. Many seem related to the openCL.dll as well as other files that seem related to the Nvidia driver.

I have 4 other PCs running Win10 and they all pass 'SFC /scannow' without any problems.

Have any other folks noticed anything strange about Nvidia drivers?

Next step is to do a refresh install and run 'SFC /scannow' before the video driver installs...
