CompTIA A+ Core 2 (220-1002) — Question 342

A technician performed an in-place upgrade to Windows 10 on a customer's laptop. Following the upgrade, a proprietary software application no longer works. The technician realizes the software is not compatible with Windows 10. Which of the following is the BEST option to make the software functional again?

Answer options

• A. Apply all known updates to the updated OS.
• B. Roll back the in-place upgrade to the original OS.
• C. Run the application in compatibility mode.
• D. Reinstall the original OS.

Correct answer: C

Explanation

Running the application in compatibility mode allows it to operate as if it were on the original OS, which can resolve compatibility issues. Applying updates may not fix the problem if the software is inherently incompatible with Windows 10. Rolling back the upgrade or reinstalling the original OS are more drastic measures that may not be necessary if compatibility mode is effective.
