The System File Checker (SFC) has been a staple of Windows operating systems for many years, providing users with a powerful tool to maintain the health and integrity of their system files. By scanning your Windows 10 system files and verifying their integrity, SFC can automatically repair any corrupt files it finds. This can significantly improve the stability and performance of your computer. In fact, according to Microsoft, SFC can fix about 90% of issues related to corrupted system files. So, if you're encountering strange errors or experiencing system instability, running SFC should be one of your first troubleshooting steps.

Understanding System File Checker in Windows 10

The System File Checker (SFC) is a built-in tool in Windows 10 that allows users to scan and restore corrupted system files. It scans the protected system files and replaces any incorrect versions with the correct ones from the Windows installation media or a cached copy stored on the local disk. Running the System File Checker can help resolve various issues, such as system crashes, application errors, and missing or damaged system files.

Starting the System File Checker

To start using the System File Checker in Windows 10, you need to open the Command Prompt as an administrator:

• Press the Windows key + X and select "Command Prompt (Admin)".
• If prompted, enter your administrator password or give permission to continue.

Once you have opened the Command Prompt as an administrator, you can proceed to run the System File Checker.

Running the System File Checker

To run the System File Checker, follow these steps:

• In the Command Prompt window, type sfc /scannow and press Enter.
• Wait for the scan to complete. It may take some time to finish. Do not close the Command Prompt window during this process.
• If the System File Checker finds any corrupted files, it will attempt to repair them automatically using cached copies stored on your hard drive or the Windows installation media.
• Once the scan and repair process is complete, you will see a message indicating whether any errors were found and repaired.
• You can view the detailed log of the scan results in the CBS.log file located in the %windir%\Logs\CBS folder.

Using DISM to Repair System Image

If the System File Checker cannot repair the corrupted files, you can try using the Deployment Image Servicing and Management (DISM) tool to repair the system image:

• Open Command Prompt as an administrator.
• Type dism /online /cleanup-image /restorehealth and press Enter.
• DISM will connect to Windows Update to download any necessary files to repair the system image.
• Wait for the process to complete, and then run the System File Checker again to check if the issue has been resolved.

Additional Tips and Considerations

Here are a few additional tips and considerations when using the System File Checker in Windows 10:

• Ensure that you have administrative privileges to run the System File Checker and DISM tool.
• If the System File Checker cannot repair the corrupted files, you may need to consider performing a Windows Repair installation or a clean installation of Windows.
• Always keep your Windows installation media or recovery drive handy in case you need to provide the required files for repairing system files.
• Regularly run the System File Checker to check for and repair any corrupted system files, even if you are not experiencing any issues. This can help prevent future problems.
• Make sure to update your Windows operating system and applications regularly to minimize the risk of system file corruption.
