Windows 10: What to do when both SFC and DISM scans cannot restore corrupted system files?

In December, a Windows 10 update corrupted some system files on my computer i7, 3.7 GHz, 16GB, 64-bit, Windows 10 Home, 22H2, build 19045.3693. Since then, I have run, as Administrator. from cold boot, multiple scans with SFC /SCANNOW and all three levels of DISM CheckHealth, ScanHealth and RestoreHealth. All SFC and DISM scans hang at 47.8%, reporting that they cannot restore some corrupted system files. Several more recent Windows 10 updates have occured, but have not fixed the corrupted system files. Almost all programs are randomly failing to respond to commands, or pause interminably

Windows 10 wont boot, repair, reset, or system restore

Hi,

The issue occurs due to an
unfinished update process which
corrupted the system files. We suggest that you try these troubleshooting
methods and run the update again:

Method 1:
Run SFC Scan.

To run an
SFC scan, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type
  sfc /scannow
  and hit
  Enter.
  

This will check and run an auto-repair on the issue.

Method 2:
Run DISM Tool.

After running the
SFC scan
and the issue still persist, run the
DISM
to check the system health and to try restoring the files. To run
DISM tool, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type the following command:
  
  • 
    DISM.exe /Online /Cleanup-image /scanhealth
    
  • 
    DISM.exe /Online /Cleanup-image /Restorehealth
    

NOTE:
This might take a while
to finish scanning.
Do not cancel.

Let us know how it goes.

Regards.

 

SFC scan and DISM restorehealth scan

I 've seen some cases where:

SFC doesn't report corruption

DISM reports corruption.

Also,

There were some reports last year where SFC reported corrupt files but that wasn't true.

So this system isn't truly reliable.

I would not bother if the system works fine though the SFC Scan reports corruption.

 

SFC scanning is not fixing the corrupted files & how to replace it?

Try method 2 first then method 1 again.

Method 1:

System file checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.
Run system file checker (SFC) and see if it helps. Please follow these steps:
a. Press Windows + X keys and click command prompt (admin). Or PowerShell (Admin).
b. Type the following command in command prompt and press Enter.
sfc /scannow

If it does not help, use method 2.
Method 2:

Run DISM tool and check the issue. Please follow these steps:
a. Press Windows + X keys and click command prompt (admin). Or PowerShell (Admin).
b. Type the following command in command prompt and press Enter.
DISM.exe /Online /Cleanup-image /Scanhealth

after the scan is complete type the following and press Enter

DISM.exe /Online /Cleanup-image /Restorehealth
