How to Run a SFC Scan on Windows 10
Running an SFC (System File Checker) scan on Windows 10 is a simple process that helps you identify and fix corrupted system files. You just need to open the Command Prompt with administrative privileges and enter a specific command. The scan will run and automatically repair any issues it finds. Here’s a step-by-step guide to help you through the process.
Step by Step Tutorial to Run a SFC Scan on Windows 10
Running a System File Checker (SFC) scan can detect and repair corrupt system files, making your computer run smoother and more efficiently. Follow these steps to run the scan.
Step 1: Open Command Prompt as an Administrator
Press the Windows key, type "cmd," right-click on "Command Prompt," and select "Run as administrator."
Opening Command Prompt as an administrator is crucial because the SFC scan needs elevated permissions to function correctly. If you don’t run it as an admin, the scan won’t be able to fix any issues it finds.
Step 2: Allow User Account Control (UAC) Permission
Click "Yes" when prompted by the User Account Control (UAC).
This step confirms that you want to allow Command Prompt to make changes to your device, which is necessary for the SFC scan to repair system files.
Step 3: Enter the SFC Command
Type sfc /scannow and press Enter.
This command initiates the System File Checker scan. It will start scanning your system files and will automatically fix any corrupted ones it finds.
Step 4: Wait for the Scan to Complete
Do not close the Command Prompt window until the verification is 100% complete.
The scan can take some time, depending on your system’s speed and the number of files being scanned. Be patient and avoid interrupting the process to ensure all issues are detected and repaired.
Step 5: Review the Scan Results
Once the scan is complete, review the results displayed in the Command Prompt window.
The results will inform you if any corrupt files were found and whether they were fixed. If issues are found but not fixed, you may need to run additional troubleshooting steps.
After you complete the SFC scan, your system should run more smoothly, as any corrupted files detected will be repaired. This process can significantly improve system performance and stability.
Tips for Running a SFC Scan on Windows 10
- Ensure you run Command Prompt as an administrator to grant the necessary permissions for the scan.
- Close all other applications before running the scan to avoid conflicts and ensure the process runs smoothly.
- Allow the scan to complete without interruption to ensure all files are properly scanned and repaired.
- If the SFC scan doesn’t fix the issue, consider running the DISM (Deployment Imaging Service and Management Tool) command for further troubleshooting.
- Regularly running SFC scans can help maintain system integrity and performance over time.
