Examples

Example 1: Modify a trigger in a scheduled task

In this example, the first command uses the New-ScheduledTaskTrigger cmdlet to define a time trigger, to which the $Time variable is assigned.

The second command adds (or replaces) the $Time trigger in the scheduled task SoftwareScan.

PS C:\> $Time = New-ScheduledTaskTrigger -At 12:00 -Once
PS C:\> Set-ScheduledTask –TaskName "SoftwareScan" –Trigger $Time

Example 2: Modify settings in a scheduled task definition

In this example, the set of commands uses cmdlets and variables to modify a scheduled task.

In this example, the first command uses the New-ScheduledTaskAction cmdlet to define an action, to which the $A1 variable is assigned.

The second command uses the New-ScheduledTaskAction cmdlet to define a second action, to which the the $A2 variable is assigned.

The third command adds the two actions to the scheduled task DeployTools.

PS C:\> $Act1 = New-ScheduledTaskAction -Execute Notepad.exe
PS C:\> $Act2 = New-ScheduledTaskAction -Execute Calc.exe
PS C:\> Set-ScheduledTask "DeployTools" -Action $A1,$A2
