Running System File Checker on Windows 10 can help you fix corrupted files and improve your computer’s performance. It’s a straightforward process involving running a command in the Command Prompt. In this guide, I’ll walk you through each step to ensure your system files are in top shape.
How to Run System File Checker on Windows 10
System File Checker (SFC) is a useful tool that scans and restores missing or corrupted system files on Windows 10. Follow these steps to complete this task efficiently.
Step 1: Open Command Prompt as Administrator
First, click on the Start button and type "cmd" in the search bar.
When you see "Command Prompt" in the results, right-click on it and select "Run as administrator." This will give you the necessary permissions to run the System File Checker.
Step 2: Run the System File Checker Command
Type "sfc /scannow" in the Command Prompt window and hit Enter.
This command starts the scanning process. It might take some time, so be patient. The tool will automatically detect and fix any issues with your system files.
Step 3: Wait for the Scan to Complete
Let the scan run its course without interrupting it.
Depending on your system, the scan can take anywhere from a few minutes to an hour. You’ll see the progress in the Command Prompt window.
Step 4: Review the Scan Results
Once the scan is complete, check the Command Prompt for results.
The tool will either tell you that no integrity violations were found, or it will provide details on the files it repaired. If issues were found but not fixed, you might need to run the scan again in Safe Mode.
Step 5: Restart Your Computer
After the scan and any repairs, restart your computer.
Rebooting ensures that all changes take effect and helps your computer run smoothly.
After you complete the scan and restart your computer, your system should be more stable. Any corrupted files found would have been replaced, and your computer should run more efficiently.
Tips for Running System File Checker on Windows 10
- Ensure your computer is connected to a power source during the scan to avoid interruptions.
- Run the scan in Safe Mode if the tool doesn’t fix all issues on the first run.
- Consider running the DISM tool before running SFC if you encounter persistent problems.
- Keep your system updated to minimize the risk of file corruption.
- Backup important files before running the scan, just in case something goes wrong.
