How to Run System File Checker (SFC) in Windows to Fix Corrupted System Files

If your Windows PC is showing errors or acting unpredictably, running the System File Checker (SFC) tool is a fast and effective way to detect and repair corrupted or missing system files. Follow these simple steps to run SFC and improve your system stability.

Step 1: Open Command Prompt as Administrator

Type “Command Prompt” in the Windows search bar, right-click the result, and select Run as administrator. This opens an elevated Command Prompt window with the necessary permissions.

Step 2: Run the SFC Scan

In the Command Prompt window, enter the following command and press Enter:

“`

sfc /scannow

“`

The System File Checker will begin scanning all protected system files and automatically repair any corrupted or missing files it detects. You can also run SFC using Windows Recovery Media if your computer cannot boot normally.

Step 3: Wait for the Scan to Complete

Allow the scan to reach 100% without interruption. This ensures that all repairs finish properly.

What SFC Does

SFC compares your current system files against a cached copy stored in the `%WinDir%System32dllcache` folder. If any files are damaged or missing, SFC replaces them with the correct versions from the cache.

Possible SFC Scan Results

  • No integrity violations found: Your system files are intact.
  • Corrupted files repaired: SFC fixed the issues automatically.
  • Corrupted files found but not repaired: You may need to manually fix problems using the CBS log.

Step 4: Review the CBS Log (If Needed)

If SFC reports it couldn’t fix some files, check the detailed log file located at:

“`

%WinDir%LogsCBSCBS.log

“`

This log provides insights on files that require manual attention.

Pro Tips for Running SFC

  • Always install the latest Windows updates before running SFC to ensure maximum compatibility and repair success.
  • Restart your PC after the scan completes to apply any system file repairs.
  • If problems persist, consider running the Deployment Image Servicing and Management tool (DISM) for advanced repairs.

Repairing Windows Images With DISM

How to Repair Windows System Images Using DISM Tool

One of the most effective ways to fix deep Windows system issues is by using the Deployment Image Servicing and Management (DISM) tool. To get started, open Command Prompt as an administrator.

Begin by running a quick corruption check with the command:

`DISM /Online /Cleanup-Image /CheckHealth`

For a more thorough scan, use:

`DISM /Online /Cleanup-Image /ScanHealth`

Note that this process may take several minutes. These commands only detect corruption; they don’t repair it. The DISM tool is also capable of preparing, modifying, and repairing system images used in environments like Windows PE, Windows Setup, and the Windows Recovery Environment.

To repair corrupted Windows image files, run the following command:

`DISM /Online /Cleanup-Image /RestoreHealth`

By default, DISM fetches repair files from Windows Update. If your device is offline or Windows Update is unavailable, specify a local repair source using the `/Source:` parameter. For example, you can use the `install.wim` file from a mounted Windows ISO.

Combine this with the `/LimitAccess` switch to prevent DISM from contacting Windows Update. Make sure the repair source matches your installed Windows version to avoid compatibility issues.

If the repair process fails, try running DISM in Safe Mode and review the log file located at `%windir%LogsDISMdism.log` for detailed error information. Always run DISM commands with administrator privileges to ensure successful execution.

Using DISM is a powerful way to maintain and repair your Windows system image, helping to resolve issues without a full system reinstall.

For comprehensive Windows repair, combine DISM with the System File Checker (SFC) tool. Stay updated with the latest Windows maintenance tips to keep your system running smoothly.

Checking and Repairing Disk Errors Using CHKDSK

How to Check and Repair Disk Errors in Windows Using CHKDSK

CHKDSK (Check Disk) is a powerful built-in Windows utility designed to diagnose and repair disk errors, helping to improve your PC’s stability and performance. This tool scans your hard drive for file system errors and bad sectors, ensuring your data remains safe and your system runs smoothly.

To use CHKDSK, open Command Prompt as an administrator. Type the command `chkdsk C: /f` to fix logical file system errors on the C: drive. For a more comprehensive scan that locates and recovers bad sectors, use `chkdsk C: /r`. You can also add the `/x` parameter to force the drive to dismount before the scan begins, which is useful if the drive is currently in use.

If the drive is active, CHKDSK will ask you to schedule the disk check during your next system reboot. Depending on your disk size and the number of errors, the process may take from several minutes to several hours.

Avoid interrupting CHKDSK during its operation to prevent potential data loss. If you experience frequent hangs or CHKDSK failures, it could indicate serious hardware problems, and you might need to consider replacing the hard drive.

Before running CHKDSK, always back up your important files to protect against accidental data loss during repairs. Using CHKDSK regularly can keep your Windows PC running efficiently and help prevent unexpected disk failures.
