Running System File Checker in Windows
| Step | Description |
|---|---|
| 1 | Open Command Prompt as an administrator. You can do this by searching for “cmd” in the Start menu, right-clicking on Command Prompt, and selecting “Run as administrator.” |
| 2 | Once Command Prompt is open, type the following command and press Enter: sfc /scannow |
| 3 | The System File Checker will begin scanning your system files for any issues. This process may take some time to complete. |
| 4 | Once the scan is complete, you will receive a message indicating whether any corrupted files were found and repaired. If any issues were found, you may need to restart your computer for the changes to take effect. |
Alternative Methods to Repair Files
To repair Windows system files using alternative methods, you can run the Deployment Image Servicing and Management (DISM) tool alongside the System File Checker (SFC) scan. First, open an elevated Command Prompt by right-clicking the Start button and selecting “Command Prompt (Admin). ” Next, type “DISM /Online /Cleanup-Image /RestoreHealth” and press Enter to run the DISM tool. This will repair any corrupted system files that SFC scan couldn’t fix.
After running DISM, run the SFC scan again by typing “sfc /scannow” in the Command Prompt and pressing Enter. This will ensure that all system files are repaired and your Windows operating system is in good condition.
Using Windows Recovery Media for Repair
1. Insert your Windows Recovery Media into your computer.
2. Restart your computer and boot from the recovery media.
3. Select your language and keyboard layout preferences.
4. Click on “Repair your computer” and select “Troubleshoot” from the options.

sfc /scannow
6. Press Enter and wait for the System File Checker to scan and repair any corrupted system files.
7. Once the process is complete, restart your computer and remove the recovery media.
8. Your Windows system files should now be repaired and your computer should be running smoothly.
Understanding and Analyzing Log Files
- Log files contain records of events that occur in an operating system or software application.
- Understanding log files can provide valuable insight into system performance and potential issues.
- Log files can help identify errors, warnings, and other important events that may impact system stability.
- Analyzing log files involves reviewing the content, identifying patterns or trends, and troubleshooting any reported issues.
- Tools such as Event Viewer in Windows can be used to view and analyze log files in a user-friendly interface.
- Regularly monitoring log files can help prevent system crashes, data loss, and other problems.
Additional Repair Options and Conclusion
Additional Repair Options: If the SFC scan did not resolve the issues with your Windows system files, you can try running the DISM tool to repair the Windows image. Open Command Prompt as an administrator and type “dism /online /cleanup-image /restorehealth” to run the tool.
If you are still experiencing problems, you can also consider using System Restore to revert your system back to a previous working state. Type “rstrui” in the Run dialog box to open System Restore.
Conclusion: Repairing Windows system files with the SFC scan is a useful tool for fixing corrupted or missing files.
