- B
Use Reset this PC and choose the option to keep personal files
- C
Run Startup Repair from the Windows Recovery Environment
- D
Use System Restore to return the system to an earlier restore point
Show answer and explanation
Correct answer: B
Explanation
The best answer is to use Reset this PC with the option to keep personal files. For A+ Core 2, candidates should distinguish between repair tools and true reinstallation methods. A clean installation is more destructive and is appropriate when data is already backed up or must be removed. Startup Repair addresses boot issues only, and System Restore reverts configuration changes rather than reinstalling the operating system. Microsoft documents Reset this PC as a built-in recovery feature that can reinstall Windows while preserving user files, making it the most appropriate choice when the goal is to restore OS reliability without wiping personal data.
- A. Incorrect.
This would reinstall Windows, but deleting existing partitions removes user data unless it was backed up elsewhere first. It is a valid option when a full wipe is required, but it does not meet the stated requirement to preserve the user’s personal files on the device.
- B. Correct.
This is the best answer. In Windows 10/11, Reset this PC with the 'Keep my files' option reinstalls Windows while preserving the user’s personal files. It is specifically designed for situations where the OS is unstable or corrupted but user data should remain intact. Applications and settings are typically removed, so the technician should still confirm what will be affected.
- C. Incorrect.
Startup Repair is intended to fix boot-related problems, such as damaged boot configuration data or startup files. It is not the best choice for a system with ongoing instability caused by malware and repeated failed repair attempts. It also does not perform an OS reinstallation.
- D. Incorrect.
System Restore can roll back system files, drivers, and some settings to an earlier point in time, but it is not a full OS reinstallation method. It may help with recent changes, but it is less reliable in a heavily compromised system and depends on restore points being available and unaffected.
