- Running SFC may require a restart if it finds and repairs files, and some repairs may not be possible if the system is heavily corrupted.
FAQ

If SFC cannot repair some files, you can try running the DISM tool with the command 'DISM /Online /Cleanup-Image /RestoreHealth' before running SFC again.
Can I run SFC in Safe Mode?
Yes, running SFC in Safe Mode can help if you are experiencing issues that prevent it from running normally.
How often should I run the SFC tool?
It's a good practice to run SFC if you notice system instability, but there is no need to run it regularly unless issues arise.
