The Register-ScheduledTask cmdlet registers a scheduled task definition on a local computer.

You can register a task to run any of the following application or file types: Win32 applications, Win16 applications, OS/2 applications, MS-DOS applications, batch files (*.bat), command files (*.cmd), or any properly registered file type.


-Action <CimInstance[]>

  • This value is required

Specifies an array of one or more work items for the task to run. If you specify multiple actions, the computer runs them in order. You can specify up to 32 actions.

-CimSession [<CimSession[]>]

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-Description [<String>]

Briefly describes the task.

-Force [<SwitchParameter>]

Instructs the cmdlet to perform the operation without prompting for confirmation.

-Password [<String>]

Specifies a password for the <run as> user. The password is ignored for the well-known system accounts.

Well-known accounts are: NT AUTHORITY\SYSTEM, NT AUTHORITY\LOCALSERVICE, NT AUTHORITY\NETWORKSERVICE, and the well-known security identifiers (SIDs) for all three accounts.

-Principal [<CimInstance>]

Specifies the security context in which a task is run.

-RunLevel [<RunLevelEnum>]

Specifies the required privilege level to run tasks that are associated with the principal.

-Settings [<CimInstance>]

Specifies a configuration that the Task Scheduler service uses to determine how to run a task.

-TaskName <String>

  • This value is required

Specifies the name of a scheduled task.

-TaskPath [<String>]

Specifies the path for a scheduled task in Task Scheduler namespace. You can use \ for the root folder. If you do not specify a path, the cmdlet uses the root folder.

-ThrottleLimit [<Int32>]

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShellr calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-Trigger [<CimInstance[]>]

Specifies an array of one or more trigger objects that start a scheduled task. A task can have a maximum of 48 triggers.

-User [<String>]

Specifies the name of the <run as> user account to use when you run the task.

-Xml <String>

  • This value is required
  • Accepts pipeline input ByValue

Specifies the XML string that contains a task definition.


This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

  1. Register a scheduled task:
    PS C:\>  $Time = New-ScheduledTaskTrigger -At 12:00 -Once PS C:\>  $User = "Contoso\Administrator"
    PS C:\>  $PS = PowerShell.exe
    PS C:\>  Register-ScheduledTask -TaskName "SoftwareScan" -Trigger $Time -User $User -Action $PS
       In this example, the set of commands uses cmdlets and variables to define and register a scheduled task.

    The first command uses the New-ScheduledTaskTrigger cmdlet to assign a time trigger to the $Time variable.

    The second command assigns the $User variable to the user account name (Contoso\Administrator).

    The third command assigns the $PS variable to PowerShell.exe. This variable is used to define a task action.

    The fourth command registers a scheduled task that is named SoftwareScan in the root folder. The registered task uses the pre-created action and trigger values that are specified by the $Action and $User variables.
