A user reports that they cannot save a file in their word processing software, but yesterday the software was working fine. Which of the following tools would a technician use to BEST resolve this…

System Restore rolls back installed programs, system files, and registry entries to a snapshot taken before the problem started, directly undoing whatever software or configuration change broke the word processor's save functionality while preserving user data files.

Anti-malware software targets malicious code; while malware can cause application issues, it is not the most likely cause when a single application stops working without other infection indicators.

Recovery Console is intended for severe OS-level failures requiring command-line repair, not for resolving application-level functionality problems.

Event Viewer is a diagnostic and logging tool that can identify errors but cannot itself resolve application issues.
