Which Windows services speed up OS and application startup by caching frequently used files and components?

• A. Prefetch and Superfetch
• B. Disk Defragmenter
• C. Windows Update
• D. System Restore

Answer: (A)

Caching frequently used files and components to speed OS and application startup. These services monitor what you open and pre-load the related data into memory so launching programs or booting the system happens from RAM rather than constantly reading from disk. The combination known as Prefetch and Superfetch preloads executable files, libraries, and other startup data based on your usage patterns, so the next time you start those programs or the system, they load faster. In newer Windows versions, this functionality is part of SysMain, but the idea remains the same: keeping hot data in RAM to reduce load times. The other options don’t focus on this caching behavior—Disk Defragmenter reorganizes data on disk for faster access, Windows Update handles updates, and System Restore creates restore points for rollback.
