Running an SFC scan on Windows 11 is like giving your computer a health check-up. It allows you to scan and repair corrupted system files, keeping your system stable and efficient. Here’s the quick run-down: open the Command Prompt as an administrator, type “sfc /scannow,” then press Enter. The scan will automatically detect and fix any corrupted files. It’s a straightforward process and should resolve many common issues, ensuring your PC runs smoothly.
How to Run SFC Scan on Windows 11
Running an SFC (System File Checker) scan on Windows 11 is a proactive step to maintain your computer’s health. The following steps will guide you through the process to ensure that any corrupted files are identified and repaired.
Step 1: Open Command Prompt
Type “cmd” in the Windows search bar and select “Run as administrator.”
By running Command Prompt as an administrator, you gain the necessary permissions to execute system-level commands. This step is crucial because without these permissions, the scan won’t run correctly.
Step 2: Start SFC Scan
Type “sfc /scannow” and hit Enter.
This command initiates the System File Checker tool, which starts scanning all protected system files. It’s the heart of the process, and though it might take some time, it’s entirely worth it.
Step 3: Wait for the Scan to Complete
Allow the scan to run its course without interruption.
Patience is key here. The scan might take a few minutes to over an hour, depending on your system’s performance and number of files. Avoid using your PC heavily during this time to ensure the scan runs smoothly.
Step 4: Review the Results
Once the scan is done, check the results displayed in the Command Prompt.
The system will inform you if it found and repaired any corrupted files. If it says it couldn’t fix some issues, you might need additional troubleshooting steps.
Step 5: Restart Your Computer
Reboot your system to apply any changes made.
A simple restart ensures that any repairs made during the scan are fully implemented. It gives your system a fresh start, often resolving lingering glitches.
Once you complete these steps, your computer will have scanned and attempted to repair any corrupted system files. This process can resolve a range of issues, from system slowdowns to application errors, by ensuring system integrity.
Tips for Running SFC Scan on Windows 11
- Regularly running an SFC scan can prevent significant issues by catching them early.
- Always ensure your device is plugged in to avoid interruptions during the scan.
- If SFC doesn’t resolve all issues, consider using DISM (Deployment Image Servicing and Management) as a complementary tool.
- Close unnecessary applications and save your work before starting the scan to prevent data loss.
- If you encounter persistent issues, check the CBS.log file for detailed error information.
