How To Scan and Repair Windows System Files

Windows system files form the foundation of your computer’s operating system, ensuring seamless functionality and allowing various software applications to operate smoothly. Over time, these files can become corrupted, leading to performance hiccups or even system crashes. Periodically scanning and repairing these files is crucial for maintaining their integrity.

Getting Acquainted with the SFC Command

The System File Checker (SFC) comes to the rescue as a built-in Windows utility designed to examine and repair system files. We’ll use the command sfc /scannow to carry out this critical task. This potent tool scans your system files for corruption or other issues and automatically repairs them, ensuring your computer’s stability.

Executing the SFC /Scannow Procedure

Ready to scan your system files? Let’s go:

  1. Right-click the Start button, or press the Windows Key + X on your keyboard.
  2. Select Powershell (Admin) or Command Prompt (Admin)
  3. Click Yes when asked to allow the program to make changes.
  4. In the Powershell/Command Prompt window, type sfc /scannow and press Enter.
  5. The scan will now start, which may take 10 to 30 minutes. You can continue using your computer while it scans.

Decoding the Scan Results

Once the scan finishes, you’ll see one of the following messages:

  • Windows Resource Protection did not find any integrity violations.” This message indicates your system files are in good shape.
  • Windows Resource Protection found corrupt files and successfully repaired them.” In this case, the SFC tool has detected and repaired the issues.
  • Windows Resource Protection found corrupt files but was unable to fix some of them.” This outcome means that the SFC tool encountered issues it couldn’t resolve.

Addressing Common SFC-Related Issues

If the SFC tool couldn’t fix some of the corrupt files, consider the following steps:

  1. Reboot your computer and try again.
  2. Run the SFC tool in Safe Mode: Restart your computer, press the F8 key before Windows starts, and choose “Safe Mode with Command Prompt.” In the Command Prompt window, type sfc /scannow and press Enter.
  3. Utilize the DISM (Deployment Image Servicing and Management) tool: Open an elevated Command Prompt and type DISM /Online /Cleanup-Image /RestoreHealth, followed by Enter. This command checks for system corruption and repairs it using Windows Update. Afterward, rerun the SFC command.

In conclusion, regularly scanning and repairing Windows system files with the SFC tool can help maintain your computer’s stability and prevent potential issues. This step-by-step guide should empower you to execute the process confidently and resolve any issues that may arise. Check out our guide on How To Debloat Windows to make your computer go faster!
