Description

The New-ScheduledTaskPrincipal cmdlet creates an object that contains a scheduled task principal. Use a scheduled task principal to run a task under the security context of a specified account. When you use a scheduled task principal, Task Scheduler can run the task regardless of whether that account is logged on.

You can use the definition of a scheduled task principal to register a new scheduled task or update an existing task registration.

Examples

Example 1: Register a scheduled task by using a user ID for a task principal

The first command creates a scheduled task action named Cmd and assigns the **ScheduledTaskAction** object to the Sta variable.
PS C:\>$Sta = New-ScheduledTaskAction -Execute "Cmd"

The second command creates a scheduled task principal. The **New-ScheduledTaskPrincipal** cmdlet specifies that Task Scheduler uses the Local Service account to run tasks, and that the Local Service account uses the Service Account logon. The command assigns the **ScheduledTaskPrincipal** object to the STPrin variable.
PS C:\>$STPrin = New-ScheduledTaskPrincipal -UserId "LOCALSERVICE" -LogonType ServiceAccount

The third command registers the scheduled task Task01 to run the task action named Cmd. The **Principal** parameter specifies that the Task Scheduler uses the Local Service account to run the task. 
PS C:\>Register-ScheduledTask Task01 -Action $a -Principal $p

This example registers a scheduled task that will run as the Local Service account.

Example 2: Register a scheduled task by using a user group for a task principal

The first command creates a scheduled task action named cmd and assigns the **ScheduledTaskAction** object to the Sta variable.
PS C:\>$Sta = New-ScheduledTaskAction cmd

The second command creates a scheduled task principal. The **New-ScheduledTaskPrincipal** cmdlet specifies that Task Scheduler uses the Administrators user group that has the highest privileges to run tasks. The command assigns the **ScheduledTaskPrincipal** object to the STPrin variable.
PS C:\>$STPrin = New-ScheduledTaskPrincipal -GroupId "BUILTIN\Administrators" -RunLevel Highest

The third command registers the scheduled task Task01 to run the task action named Cmd. The **Principal** parameter specifies that Task Scheduler uses the Administrators user group to run the task.
PS C:\>Register-ScheduledTask Task01 -Action $Sta -Principal $STPrin

This example registers a scheduled task that runs under logged-in members of the Administrators user group that has the highest privileges.

-Id

Specifies the ID of a scheduled task principal.

Type:String
Position:6
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

-RunLevel

Specifies the level of user rights that Task Scheduler uses to run the tasks that are associated with the principal. The acceptable values for this parameter are:

Position:3
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ThrottleLimit

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 PowerShell® 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.
