In a Windows computing environment, which of the following tools is used to monitor system performance and resource utilization in real-time?

Performance Monitor is a built-in Windows tool that allows users to monitor the real-time performance and resource utilization of various system components such as CPU, memory, disk, and network. It provides detailed performance metrics through counters and logs, which help administrators and users identify potential bottlenecks or issues in the system. Performance Monitor is a crucial tool for system administrators to optimize and troubleshoot system performance. Option A (Event Viewer) is incorrect because Event Viewer is used to view system logs and events but does not provide real-time performance monitoring. Option B (Task Scheduler) is incorrect because Task Scheduler is used to schedule automated tasks in the system, not monitor performance. Option D (Disk Cleanup) is incorrect because Disk Cleanup is used to free up space by removing unnecessary files from the system. Option E (File Explorer) is incorrect because File Explorer is used for managing and navigating files on the system, not for performance monitoring.
