When your Windows PC encounters system issues, running the DISM and SFC tools can help repair corrupted files and restore system health. This guide will show you how to correctly run these tools to maintain your PC's performance and stability.
Understanding DISM and SFC
DISM (Deployment Imaging Service and Management) and SFC (System File Checker) are powerful tools built into Windows that help repair system images and corrupted files.
Running these tools ensures your system runs smoothly by fixing issues that could lead to crashes, slow performance, or other errors.
Using DISM and SFC to Repair System Issues
● Right-click the Start Menu
● Type and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)"
Run the First Command
● Type the following command into the Command Prompt and press Enter: DISM /Online /Cleanup-Image /ScanHealth
● This command scans your system for any corruption. It may take a few minutes to complete. Once finished, review the results to see if any issues were detected.
● If no issues are detected, you can skip directly to running the SFC scan. If DISM finds corruption, proceed to the next step to repair the system image.
Run the Second Command
● Run the following command to repair the system image: DISM /Online /Cleanup-Image /RestoreHealth
● This process can take some time, so be patient. It connects to Windows Update to download and replace the corrupted files. If successful, your system image will be repaired.
Run the Third Command
Enter the following command and press Enter: sfc /scannow
● The SFC scan will begin and may take a while. It will automatically repair any corrupted files it finds. Review the results to ensure the process was successful.
