Which tool should you open to view real-time statistics of processor and memory usage in a Windows operating system?

The tool used to view real-time statistics of processor and memory usage in a Windows operating system is Task Manager. This utility provides users with an overview of the system's performance, including details about CPU, memory (RAM), disk, and network usage. By examining the Task Manager, users can monitor how these resources are being utilized, identify which applications or processes are consuming significant amounts of resources, and manage system performance effectively.

Task Manager also allows users to end tasks that may be unresponsive or consuming excessive resources, making it an essential tool for managing system performance. Its performance tab specifically shows graphical representations of CPU and memory usage over time, aiding users in diagnosing performance issues.

Other tools mentioned, like Control Panel, Disk Cleanup, and System Information, serve different purposes and do not provide real-time monitoring of processor and memory usage. Control Panel is primarily for system configuration, Disk Cleanup is used to free up disk space, and System Information offers detailed specifications of the system but lacks real-time monitoring capabilities.
