Which Windows command is used to scan and repair corrupted system files?

• A. sfc /scannow
• B. chkdsk
• C. ipconfig
• D. dism

Answer: (A)

The command to scan and repair corrupted system files is System File Checker with the /scannow option. It checks all protected Windows system files and replaces any corrupted or missing copies with good versions from the Windows component store. You typically run it from an elevated command prompt, and it may take some time to complete. If it finds issues it can fix automatically; if it reports that it found problems but couldn’t repair them, you can follow up with DISM to repair the Windows image and then run the check again. The other commands perform different tasks—checking the disk for filesystem errors, displaying network configuration, or servicing a Windows image—so they aren’t the direct tool for repairing corrupted system files.
