    The SFC (System File Checker) tool is a built-in Windows tool that can scan for and repair missing or corrupted system files. If the SFC/scannow command is not working on your Windows computer, there are a few things you can try to fix the issue.

    SFC/Scannow Not Working

    1. Run the command prompt as an administrator: Right-click on the Start button and select “Command Prompt (Admin)”. Then, type “SFC/scannow” and press Enter.
    2. Run the command in Safe Mode: Restart your computer and press the F8 key to enter Safe Mode. Once in Safe Mode, open the Command Prompt and run “SFC/scannow”.
    3. Check for malware: Run a full system scan using your antivirus software. Malware can sometimes interfere with the SFC/scannow tool.
    4. Repair Windows using an installation media: If the above steps do not work, you may need to repair Windows using an installation media, such as a Windows installation disc or USB drive.

    It is also possible that the sfc /scannow command is not working due to a corrupt or missing system file, in this case, you may need to use the DISM command to repair the system image.

    SFC/scannow Not Working Run As Administrator

    If the sfc/scannow command is not working even when run as an administrator, there are a few additional steps you can try:

    1. Run the command in Safe Mode with Command Prompt: Restart your computer and press the F8 key to enter Safe Mode. Once in Safe Mode, open the Command Prompt and run “sfc /scannow”.
    2. Check the CBS.log file: The sfc/scannow command creates a log file named CBS.log in the C:\Windows\Logs\CBS folder. This file contains information about the files that were scanned and any errors that were found. Reviewing this log file can help you identify the specific problem that is preventing sfc/scannow from working.
    3. Repair Windows using an installation media: If the above steps do not work, you may need to repair Windows using an installation media, such as a Windows installation disc or USB drive.
    4. Run the DISM command: If the SFC command failed to fix the issue, you can try running the DISM command. Open the Command Prompt as an administrator and run the command “DISM /Online /Cleanup-Image /RestoreHealth”
