Which Windows utility enables you to monitor running applications and their performance?

The correct choice, Task Manager, is a vital utility in the Windows operating system that allows users to monitor running applications and their performance in real-time. It provides detailed information on the CPU, memory, disk usage, and network activity for each running application. Users can see which processes are currently active, their resource consumption levels, and the ability to terminate unresponsive applications. This is particularly useful for troubleshooting performance issues or managing system resources effectively.

In contrast, System Info primarily provides system specifications and details about the hardware and software configuration rather than monitoring application performance. Disk Management is focused on managing disk drives and partitions, which does not directly relate to application monitoring. File Explorer is used for navigating and managing files and folders, without any functionality for monitoring applications or their performance. Thus, Task Manager is the appropriate tool for overseeing running applications and evaluating their performance metrics.
