SFC reports corrupt files that cannot be repaired

Hi Jay,

For to better assist you with the SFC reports issue, we'd like to know the following:

• Have you installed any Windows updates prior to this issue?
  
• Please provide us a CBS logs for us to determine what is the file that cannot be repaired.
  

To get the logs, please follow the steps below:

• Open a Command Prompt (Admin).
  
• Copy and paste findstr /c:”[SR]” %windir%\Logs\CBS\CBS.log >”%userprofile%\Desktop\sfclogs.txt”, then hit
  Enter. (This will create a sfclogs.txt file on your desktop).
  
• Open the sfclogs.txt and check the result of SFC scan.
  

Note: SFC cannot always fix corrupted files.

We're looking forward to your reply.

 

20H2 system files corrupted on a clean Windows installation sfc /scannow

Hi,

I have noticed that sfc /scannow corrected system files. I wonder. So I tested again on a clean Windows 10 20H2 installation and run directly after sfc /scannow.

Preparation for testing:

• I used VMware Workstation 16.0.0
• I created a new virtual machine with default Windows 10 profile
• I disabled the Network Adapter, the OS has
  no internet the whole process
• I used the latest official Windows 10 ISO file Win10_20H2_English_x64.iso (md5: e80f6ce987b2bba288469e7379129e12) Build 19042.508
  
• Mounted the ISO in VMware

Installation:

• So I started to install Windows 10
• Install Now, No product key, Windows 10 Home, Language en-us, install on the unformatted 60GB drive etc.
• After reboot, I used "no internet" for local Account, name: admin, no password, disabled all the telemetry trash

After successful start, I started directly cmd.exe with administrator privilegs and run sfc /scannow.

It will found corrupted systems files.





It didn't let me post the log here, so I made a Screenshot.

What is going on here?

I repeated the steps with de_windows_10_business_editions_version_20h2_x64_dvd_ce126f3b.iso (md5: 35df62707e53c2064641ccd5b91acb8d)

Type license: Enterprise

After repeating the steps above, the result is the same.

 

SFC reports corrupt files that cannot be repaired

My Surface Pro 4 does not appear to have any problems. But I periodically run System File Check. SFC now reports corrupt files that it cannot repair. I've tried running DISM using the basic restorehealth options. This never has worked without downloading
a fresh .iso copy of Windows, which is no longer available for download. I even tried the DISM from the repair environment. It ran successfully, but SFC still reports corrupt files that it cannot repair. What should I do? I don't want the Windows OS files
on my Surface to be corrupt. From the number of posts on this forum, this must be a common problem. None of the threads I've read suggests anything that I haven't already tried. As I said above, most of the suggestions involve running DISM without referring
to an ISO file. That's strange, since I've never seen that work.
