CompTIA A+ 220-1102 Practice Question

The System File Checker (SFC) tool is a built-in utility in Windows that scans and replaces corrupted or missing system files with healthy ones. It is a common troubleshooting step to run SFC when experiencing system instability, BSOD, or other system file-related issues. It is not a tool for updating drivers or applications, nor is it a tool for scanning for malware.
