A user reports that their Windows 10 PC takes over 5 minutes to boot. Which tool helps identify startup programs causing delays?

Correct answer: Task Manager Startup tab

Option A is correct because the Task Manager Startup tab (accessible via Ctrl+Shift+Esc, then the Startup tab) lists every program that launches at boot along with its startup impact rating, allowing a technician to identify and disable high-impact culprits directly. Option B is incorrect because Disk Management is used to partition, format, and manage storage volumes; it provides no visibility into startup programs or boot time contributors. Option C is incorrect because Device Manager lists hardware devices and their drivers, which is useful for driver issues but does not surface software startup entries or their boot-time impact. Option D is incorrect because Performance Monitor can record detailed system counters over time for advanced analysis, but for a quick identification of startup program delays the Task Manager Startup tab is the simpler and more direct tool.
