A technician is troubleshooting a Windows 10 workstation where a recently installed application is crashing frequently. The technician suspects that system files might have been corrupted during the application's installation. Which built-in Windows utility should the technician use to scan for and restore corrupted system files?
- ASFC (System File Checker)
- BDisk Management
- CCHKDSK
- DDISM
Show answer & explanationAnswer & explanation
Correct answer: A. SFC (System File Checker)
The System File Checker (SFC) is a Windows utility specifically designed to scan for and restore corrupted or missing protected system files. It is the primary tool for addressing issues related to system file integrity.
Why the other options are wrong
- B. Disk Management is used for partitioning, formatting, and managing disk drives, not repairing system files.
- C. CHKDSK (Check Disk) scans and repairs issues with the file system on a disk, not specifically system files.
- D. DISM (Deployment Image Servicing and Management) is used to repair Windows images, which can be a prerequisite for SFC or used when SFC fails, but SFC is the direct tool for active system files.
System File Checker (SFC)
A Windows command-line utility that scans for and restores corrupted or missing protected system files.
- Run via 'sfc /scannow' in an elevated Command Prompt.
- Compares current system files against known good versions.
- Helps resolve issues caused by corrupted OS files.
Memory trick: SFC Saves Files from Corruption.
