Difference-Between-SFC,-CHKDSK,-and-DISM-Windows-11.txt

My suggestions:
1) Backup your hard drive - run  Administrative Command Prompt
   and create a Restore Point

2) run Administrative Command Prompt and then enter:  sfc /scannow
   may take 5-25 minutes

3) If no UNcorrectable errors, run Administrative Command Prompt and
   then enter:
      CHKDSK /F 



SFC analyzes your system files while CHKDSK searches your hard drive
 and DISM scans and patches faulty files in the component store of
the Windows system image, allowing SFC to function correctly.

Make a backup of your disk partition before executing DISM, just in
case anything goes wrong during the process.

Difference Between SFC, CHKDSK, and DISM Windows 11

SFC analyzes your system files while CHKDSK searches your hard drive and
DISM scans and patches faulty files in the component store of the Windows
system image, allowing SFC to function correctly. Make a backup of your
disk partition before executing DISM, just in case anything goes wrong
during the process:

When the System File Checker (SFC) cannot resolve issues on a computer,
the DISM utility is often employed. The DISM tool can repair Component
Store Corruption, which is known to hinder SFC Scan from operating correctly
on a computer when it is used.

Keep in Mind: If SFC is corrupted and does not function properly for whatever reason, you can restore it using DISM. To enable DISM, you only need to do the steps outlined below.

Step 1: By right-clicking Command Prompt and select Run as administrator,
   you can start Command Prompt as an administrator.

Important: Type the Following Command: DISM /Online /Cleanup-Image /RestoreHealth

Step 2: To execute the command, press the Enter key.

Step 3: For it to complete the scan, which can take anywhere from five to 10 minutes,
        sometimes even longer.

Step 4: As soon as DISM has completed scanning your computer, restart your computer.

Notification: Don't worry if the progress meter seems to be stopped at 20 percent;
   this is quite normal; you need to be patient.

What is the Difference Between SFC, CHKDSK, and DISM?

SFC analyzes your system files while CHKDSK searches your hard drive and DISM scans
and patches faulty files in the component store of the Windows system image, allowing
SFC to function correctly. 

Make a backup of your disk partition before executing DISM, just in case anything
goes wrong during the process.

To execute DISM, you'll need to start a Command Prompt with elevated privileges,
just as you did with CHKDSK and SFC. You can first determine whether or not the
picture is corrupted without making any modifications, which will save you time
and the chance of doing fixes that aren't necessary.

Conclusion

Now that you know what CHKDSK, SFC, and DISM perform, you can try running one
or more of these Windows troubleshooting tools to see if they can assist you
in fixing your computer.

If you're still experiencing problems, you can try a System Restore procedure.
In this case, your system data, configurations, and applications will be
restored to a previous state in which they were operational.
