A user regularly calls and states that they have a computer with possibly corrupt system files and wants to know how to repair them. Which of the following utilities would resolve the problem?

ASR (Automated System Recovery) is a Windows XP backup and recovery feature used to restore the system from a backup set - it does not scan or repair individual corrupt files.

FIXMBR is a Recovery Console command used to repair the Master Boot Record on a disk - it addresses boot sector issues, not corrupt system files within the OS.

SFC (sfc /scannow) scans the Windows system file cache and replaces corrupted protected system files with known good cached copies. It is the correct and recommended utility for resolving corrupt system file issues without requiring a full reinstall of the operating system.

MSCONFIG (System Configuration utility) manages startup programs, services, and boot options but cannot detect or repair corrupt system files.
