CompTIA A+ Core 2 (220-1102) — Question 346

A user is unable to access several documents saved on a work PC. A technician discovers the files were corrupted and must change several system settings within Registry Editor to correct the issue. Which of the following should the technician do before modifying the registry keys?

Answer options

• A. Update the anti-malware software.
• B. Create a restore point.
• C. Run the PC in safe mode.
• D. Roll back the system updates.

Correct answer: B

Explanation

Creating a restore point is essential because it allows the technician to revert the system back to a previous state if the modifications to the registry lead to further issues. The other options, while potentially useful, do not directly safeguard against problems that may arise from editing the registry.
