Running an SFC scan on Windows 10 is a straightforward process that helps you repair corrupted system files. By following a few simple steps, you can ensure your computer is running optimally.
How to Run SFC Scan in Windows 10
Running an SFC (System File Checker) scan on Windows 10 will help you find and fix corrupted system files. This could be a lifesaver if your system is acting weird or you’re facing unexpected crashes. Follow these steps to run an SFC scan effectively.
Step 1: Open Command Prompt as 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 it grants the necessary permissions to execute the SFC command. If you skip this step, the scan might not run correctly.
Step 2: Type the Command
In the Command Prompt window, type sfc /scannow
and press Enter.
This command initiates the System File Checker scan. The "/scannow" option tells the tool to scan all protected system files and repair any issues it finds.
Step 3: Wait for the Scan to Complete
The scan may take some time, so be patient and do not close the Command Prompt window.
The duration of the scan depends on your system’s performance and the number of files it has to check. It’s important to let the process complete without interruption.
Step 4: Review the Results
Once the scan is finished, Command Prompt will display a message indicating whether any issues were found and if they were fixed.
You might see messages like "Windows Resource Protection did not find any integrity violations" or "Windows Resource Protection found corrupt files and successfully repaired them." This information helps you understand what has been fixed.
Step 5: Restart Your Computer
After the scan, it is advisable to restart your computer to apply any fixes.
Restarting your system ensures that any repairs made by the SFC scan are fully implemented, giving your system a fresh start.
After completing these steps, your system files should be repaired and your computer might run smoother.
Tips for Running SFC Scan in Windows 10
- Make sure your system is plugged into a power source if you’re using a laptop. The scan can be long, and you don’t want it to be interrupted by a dead battery.
- Run the scan in Safe Mode if you encounter issues. Sometimes, running SFC in Safe Mode can resolve problems that occur in normal mode.
- Consider running a DISM scan before SFC if you’re experiencing persistent issues. This can repair the Windows image before SFC attempts to fix system files.
- Regularly update Windows to minimize the risk of system file corruption.
- Use SFC cautiously; it’s a powerful tool but should not be overused.
