In Windows, what utility is used for disk management tasks?

The Disk Management tool is the correct choice for performing disk management tasks in Windows. This utility allows users to manage the hard drives installed on their system and includes functionalities such as creating, deleting, resizing, or formatting partitions. Through the Disk Management interface, users can also change drive letters, convert between partition types, and initialize new disks, all of which are essential for maintaining and organizing storage.

Other tools such as Device Manager, Task Manager, and Command Prompt have very different purposes. Device Manager is used for managing hardware devices and their drivers, Task Manager is focused on monitoring system resources and managing running processes, while Command Prompt is a command-line interface that can perform a variety of tasks but is not specifically designed for disk management. Therefore, the Disk Management tool is the most appropriate utility for this specific purpose.
