Description

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

You can register a task to run executable files (.exe and .com), batch files (.bat and .cmd), or any registered file type. However, this cmdlet does not check whether the file you intend it to run is compatible with your version, edition, or platform specialization of Windows.

Examples

Example 1: Register a scheduled task

PS C:\> $Time = New-ScheduledTaskTrigger -At 12:00 -Once
PS C:\> $User = "Contoso\Administrator"
PS C:\> $PS = New-ScheduledTaskAction -Execute "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 the name of the user account in the context of which the task runs (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.

Parameters

-Action

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.

Type:CimInstance[]
Position:2
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters: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 or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Description

Briefly describes the task.

Type:String
Position:8
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Force

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

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-InputObject

Specifies the input object that is used in a pipeline command.

Type:CimInstance
Position:2
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Password

Specifies a password for the user account in the context of which the task runs. 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.

Type:String
Position:4
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Principal

Specifies the security context in which a task is run.

Type:CimInstance
Position:5
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-RunLevel

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

Type:RunLevelEnum
Accepted values:Limited, Highest
Position:7
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Settings

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

Type:CimInstance
Position:4
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-TaskName

Specifies the name of a scheduled task.

Type:String
Position:0
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-TaskPath

Specifies an array of one or more paths for scheduled tasks in Task Scheduler namespace. You can use "*" for a wildcard character query. You can use \* for the root folder. To specify a full TaskPath you need to include the leading and trailing \. If you do not specify a path, the cmdlet uses the root folder.

Type:String
Position:1
Default value:None
Required:False
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.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Trigger

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