Which action can users perform using Computer Management?

Users can perform the action of scheduling tasks using Computer Management because it provides a centralized interface for managing various aspects of a computer system. The Task Scheduler, accessible through Computer Management, allows users to automate routine tasks on their computers. This includes setting up tasks to run scripts, programs, or other automation processes at specified times or in response to specific events.

The other options listed do not utilize the Computer Management interface. Customizing the taskbar typically involves accessing the taskbar settings through the Windows interface rather than through Computer Management. Opening a domain controller is usually managed through Active Directory tools and not directly through the Computer Management console. Deleting items from the Control Panel involves navigating to the Control Panel interface itself, not through Computer Management. Therefore, the ability to schedule tasks is a distinctive feature offered within the Computer Management tool.
