If SFC itself cannot fix the issue, the Deployment Image Servicing and Management (DISM) tool comes into play. DISM is a more powerful tool used to repair the underlying Windows image (the source files that SFC uses). Commands like DISM /Online /Cleanup-Image /RestoreHealth ensure the foundational files are sound before running SFC again. These tools are the safest and most effective way to restore the integrity of the operating system without resorting to risky manual replacements. They prioritize the internal consistency of the OS installation.
