A user reports that their Windows 10 computer has become extremely slow and is occasionally crashing. The IT technician suspects a corrupted Windows system file is the cause. Which of the following tools should the technician use FIRST to repair the Windows system files?
System File Checker (SFC) is a utility in Windows that allows users to scan for and restore corruptions in Windows system files. It is an ideal first step in troubleshooting a suspected issue with system file integrity, as it can identify and fix problems without impacting user data. If SFC does not resolve the issue, other tools like Windows Recovery Environment or System Restore might be considered for more comprehensive repair actions. Disk Cleanup, while useful for freeing up space and potentially improving performance, is unlikely to fix system file corruption.
