PowerShell scheduled task requirements

Below are the requirements to create scheduled tasks using PowerShell:

In our examples, in this article, we will use Windows 10. But Windows Server 2012 and newer versions can do the same.
Windows PowerShell 5.1 or PowerShell 7.
Script editor such as Visual Studio Code, Notepad++, or Windows PowerShell ISE.

Before starting you need to understand a brief explanation for each scheduled task component below:

Action – the action that is executed by the scheduled task. Action is typically to run a program or a script. A scheduled task can have more than one action.
Trigger – controls when the scheduled task runs. Triggers can be time-based, like, setting a schedule for daily or hourly recurrence. Triggers can also be activity-based, which runs a task based on detected activities like computer startup, a user logs in, or logged events.
Principal – controls the security context used to run the scheduled task. Among other things, a principal includes the user account and the required privilege used by the scheduled task.
Settings – is a set of options and conditions that controls how the scheduled task behavior. As an example, you can customize a task to get removed after a consecutive number of days that the task is unused.

Note: During a scheduled task creation, the principal and settings are not explicitly required. The default values get used instead.

How to create a scheduled task with PowerShell on Windows 10

To create PowerShell scheduled tasks on Windows 10, use these steps:

Open Start.
Search for PowerShell, right-click the top result, and select the Run as administrator option.
Type the following commands to create a variable to store the action of the task and press Enter. In the command, make sure to replace ‘PROGRAM’ with the name of the program you want to start. The “$action” is a variable, and it does not matter the name as long as you keep it short, simple, and descriptive. For example, this command tells Task Scheduler to start the Microsoft Word app:$action = New-ScheduledTaskAction -Execute ‘WINWORD.EXE’

Type the following command to create a variable that stores the schedule information for the task and press Enter. In the command, make sure to replace SETTING and TIME with the details on when you want to run the task. The $trigger is a variable, and it does not matter the name. For example, this example tells Task Scheduler to run the task daily at 7 pm:
```
$trigger = New-ScheduledTaskTrigger -Daily -At 7pm
```
In the command, make sure to update “TASK-NAME” with the task’s actual name and “OPTIONAL-DESCRIPTION-TEXT” with the description of the task. The folder “-TaskPath” option is not a requirement, but it will help keep tasks separate. If you do not specify the option with a path, the task will be created inside the Task Scheduler Library folder. For example, this command creates as a scheduled task with the “testTask” name, custom description, and with settings specified on steps No. 3 and 4:

Register-ScheduledTask -Action $action -Trigger $trigger -TaskPath "MyTasks" -TaskName "testTask" -Description "This task opens the Word"
