CompTIA A+ (220-901) — Question 32

A technician upgrades an older computer to Windows 8. The computer is running unusually slow, but the hardware has no problems and is adequate for the OS.
Which of the following is the MOST likely solution?

Answer options

• A. Change the boot sequence
• B. Switch the BIOS to UEFI
• C. Defragment the hard drive
• D. Enable virtualization

Correct answer: C

Explanation

Defragmenting the hard drive can significantly improve performance by reorganizing fragmented data, thus allowing the operating system to access files more efficiently. The other options, such as changing the boot sequence or enabling virtualization, do not directly address performance issues caused by disk fragmentation and are unlikely to resolve the slow performance in this scenario.
