What tool can run specific programs at a designated time by the user?

The Task Scheduler is a feature in Windows that allows users to schedule the execution of scripts or programs at specified times or in response to certain events. This tool provides a convenient way to automate tasks such as backups, running maintenance scripts, launching software, or performing system updates without requiring user intervention at the time for each task.

Using the Task Scheduler, a user can set triggers that determine when a task should be initiated, such as daily, weekly, or based on system events. This functionality is critical for users or administrators looking to ensure that routine tasks are performed consistently and efficiently.

The other options do not have the same scheduling capability. Services manage background applications and system components but do not offer user-defined scheduling for tasks. The Event Viewer is used for monitoring system and application events, providing logs for troubleshooting but does not manage program execution. Windows Memory Diagnostics is specifically used for testing RAM health and does not have any scheduling or program initiation functionality.
