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 ``` 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 $Sta -Principal $STPrin ``` This example registers a scheduled task that will run as the Local Service account. The first command creates a scheduled task action named Cmd and assigns the **ScheduledTaskAction** object to the $Sta variable. ### Example 2: Register a scheduled task by using a user group for a task principal ``` PS C:\>$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. The first command creates a scheduled task action named cmd and assigns the **ScheduledTaskAction** object to the $Sta variable. ## Parameters ### -AsJob Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. #### Parameter properties | Type: | SwitchParameter | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets (All) | Position: | Named | | --- | --- | | Mandatory: | False | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -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](https://go.microsoft.com/fwlink/p/?LinkId=227967) or [Get-CimSession](https://go.microsoft.com/fwlink/p/?LinkId=227966) cmdlet. The default is the current session on the local computer. #### Parameter properties | Type: | CimSession[] | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | | Aliases: | Session | #### Parameter sets (All) | Position: | Named | | --- | --- | | Mandatory: | False | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -GroupId Specifies the ID of a user group that Task Scheduler uses to run the tasks that are associated with the principal. #### Parameter properties | Type: | String | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets Group | Position: | 0 | | --- | --- | | Mandatory: | True | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -Id Specifies the ID of a scheduled task principal. #### Parameter properties | Type: | String | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets (All) | Position: | 5 | | --- | --- | | Mandatory: | False | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -LogonType Specifies the security logon method that Task Scheduler uses to run the tasks that are associated with the principal. The acceptable values for this parameter are: - None - Password - S4U - Interactive - Group - ServiceAccount - InteractiveOrPassword #### Parameter properties | Type: | LogonTypeEnum | | --- | --- | | Default value: | None | | Accepted values: | None, Password, S4U, Interactive, Group, ServiceAccount, InteractiveOrPassword | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets User | Position: | 1 | | --- | --- | | Mandatory: | False | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -ProcessTokenSidType Specifies the security ID (SID) type of the process token.

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. #### Parameter properties | Type: | Int32 | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets (All) | Position: | Named | | --- | --- | | Mandatory: | False | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### -UserId Specifies the user ID that Task Scheduler uses to run the tasks that are associated with the principal. #### Parameter properties | Type: | String | | --- | --- | | Default value: | None | | Supports wildcards: | False | | DontShow: | False | #### Parameter sets User | Position: | 0 | | --- | --- | | Mandatory: | True | | Value from pipeline: | False | | Value from pipeline by property name: | False | | Value from remaining arguments: | False | ### CommonParameters This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable, -ProgressAction, -Verbose, -WarningAction, and -WarningVariable.
