Final answer:
In Task Manager, you can perform Application management and Process management, which involve monitoring and ending unresponsive programs, as well as managing startup applications. Disk management is not a feature of Task Manager.
Step-by-step explanation:
The tasks that can be managed in the Task Manager include Application management and Process management. Specifically, the Task Manager allows users to view and manage running applications and services, end unresponsive programs, monitor system performance, and observe the processes consuming system resources. It also offers a tab for managing Startup programs, but it does not provide disk management capabilities, which typically involves partitioning, formatting, and changing drive letters, and are handled by a different tool, the Disk Management utility.
For example, if an application is not responding, you can open Task Manager, go to the 'Processes' tab, find the program, and end its process to close the application forcibly. Similarly, if you wish to stop a program from automatically starting up when you turn on your computer, you can switch to the 'Startup' tab and disable the desired application.
