How to: Run sfc scan in Windows 10

It happens a lot of time that some of the Windows system files get corrupted. This creates a hole inside the OS and leads to a mess at the end. Windows 10 has a very unique tool which helps the users to check for their corrupted or missing windows system files and also restores them to their previous states.

This is a utility tool called System File Checker. If, there is a corrupted Windows Resource protection File inside your Windows OS, you would have some difficulties in performing the SFC scan on your PC as  some of the Windows functions may not work as expected before you run SFC Scan you can also use a third party repair tool from Reimage Plus from here which can scan, restore and repair corrupt repositories. Running Reimage Plus is optional but highly recommended.

How to Run System File Checker SFC Scan using SFC Tool:

Here comes the fun part. In order to run SFC, just follow the instructions properly as mentioned below.

Go the elevated Command Prompt by right clicking on the start menu icon. Select the Command Prompt (Admin) from the list. You can also navigate to command prompt by using the shortcut keys Win + X and then, select it.

sfc scannow 1

After running the Command prompt, type the following command mentioned below in order to run SFC scan. Make sure that you don’t abort this process and wait for it to complete. The resulted will be shown after the scan is completed.

sfc /scannow

Hit Enter on the keyboard after typing. It would start scanning for corrupted or missing files on your PC.

PRO TIP: If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Reimage Plus by Clicking Here

How Does this Command Scan your PC?

This command is beneficial for those who have some issues related to file corruption of their PC. It scans all of the protected system files and replaces the corrupted files with a cached copy located in a compressed folder C:\Windows\System32\dllcache. You can navigate to this folder using the above mentioned hierarchy.

Results of SFC Scan:

After the process is finished at 100%, if everything goes well, you would get the following message Windows Resource Protection did not find any integrity violations as shown in the picture below.

sfc scannow4

If SFC Scan shows the following message Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log, then you can check the details using the following method described below.

Navigate to Command Prompt and type the following line of code followed by Enter Key on the Keyboard.

findstr /c:”[SR]” %windir%\Logs\CBS\CBS.log >”%userprofile%\Desktop\sfcdetails.txt

If you want to skip to repairing the corrupt system components type the following command and hit enter in the command prompt

Dism /Online /Cleanup-Image /RestoreHealth

The text at the end of the above command i.e. txt contains details of the whole schedule of SFC scan performed on the PC with date and time. Open the sfcdetails.txt file from the desktop and you can view the details of the scan.

If SFC Scan doesn’t resolves the issue for you, try SFCFix which is a third party tool that reads from the CBS.LOG file to repair corruptions.

    Dism /Online /Cleanup-Image /RestoreHealth

    This did not work for me. It hangs for a minute or so at 20.0% and then I get the following…

    Error: 1726
    The remote procedure call failed

    • This seems to be caused by a running process on your system. Can you go to task manager; and kill all third party programs/processes? Then run it again.

      • Kevin Priest

        Unfortunately,after trying several different suggested fixes, including this one, I finally gave up and decided to try reinstalling Windows 10. So far everything seems to be working as it should with the re-install. I intend to keep a very close eye on things this time around to see if I can pinpoint what might have led to the issue the first time around. I will keep you updated if I find anything.

        • Thank you for letting me know. I do intend to write a detailed guide for this error and will do in a couple of days.

  • I have just run this and got the following ‘Windows Resource Protection found corrupt files but was unable to fix some of them’

    • Please run this command. Dism /Online /Cleanup-Image /RestoreHealth

  • Nessie Visitacion

    Hey all, after running the scan, I get the message “Windows Resource Protection could not perform the requested operation.” Um… help please.

  • Elodie H.

    Hi,
    I tried to run the sfc scan, but it told me that I needed to reboot my system. I did but it still gives me the same message. What should I do?

    • What is the exact message you were having?

  • Nicholas Theophilus

    how do you know when the system restore is done

    • When it’s done, system will reboot and start normally. If it’s not done, you’ll get an error while it is restoring or trying to.

      • Nicholas Theophilus

        so an error like this is normal or… ?

        • Run sfc /scannow again to see what it says. And post a picture here, it will be better if we continue with this issue on http://equestions.net/ask so i can assist you more conveniently.

          • Nicholas Theophilus

            Sorry it took so long. school work
            It keeps asking to specify source, what do I do?

          • You need to mount an image of win 10 and point DISM to it. This is how

            If you get the error message “cannot find source files”you need to have an ISO file mounted and need to specify where it is located with the below command

            DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess Where “X” is the drive letter where the ISO is located. Simply change the “X” to the correct drive letter

          • Nicholas Theophilus

            still keeps saying the same thing
            could be the fact that I haven’t activated windows yet

          • Please see my last response, you need to mount iso file and refer to the location as stated above. WIM:X:SourcesInstall.wim:1 /LimitAccess Where “X” is the drive letter where the ISO is located. Simply change the “X” to the correct drive letter

          • Nicholas Theophilus

            I think I did, you mean drive like c:

          • You need to create and burn windows 10 iso, mount it and then use it’s path in the command.

          • Nicholas Theophilus

            thanks, but is there a short guide I could use

          • There is showing how to mount; but you will need to download ISO for Windows 10 Media Creation Tool. http://appuals.com/how-to-mount-an-iso-file/

          • Nicholas Theophilus

            still keeps popping up the same message.
            could this be because I changed the accounts username some time back

  • DISM.exe /Image:C: /Get-Packages

    instead of DISM.exe /Online /Get-Pacages

    /Online can only be used in windows not in the Windows Preinstallation Environment (WinPE)

    • You entered the command incorrectly. Copy / Paste it from this article.

      • Tyler Wang

        I had the same error message. re-typed it correctly but still got the very same error message

  • Beth Vance

    doing this fix allowed me to access google Chrome once more but did not solve the email issue.

    • The e-mail issue then must not be caused by the corruption of system files. It could be a different issue. I suggest you post complete details of it on equestions.net/ask

  • Please submit this as a new question on eQuestions.net/ask

  • Hopefully, if you don’t see issues.
