Not used in Get-TargetResource. .PARAMETER MultipleInstances Specifies the policy that defines how Task Scheduler handles multiple instances of the task. Not used in Get-TargetResource. .PARAMETER Priority Specifies the priority level of the task. Priority must be an integer from 0 (highest priority) to 10 (lowest priority). The default value is 7. Priority levels 7 and 8 are used for background tasks. Priority levels 4, 5, and 6 are used for interactive tasks. Not used in Get-TargetResource. .PARAMETER RestartCount Specifies the number of times that Task Scheduler attempts to restart the task. Not used in Get-TargetResource. .PARAMETER RestartInterval Specifies the amount of time that Task Scheduler attempts to restart the task. Not used in Get-TargetResource. .PARAMETER RunOnlyIfNetworkAvailable Indicates that Task Scheduler runs the task only when a network is available. Task Scheduler uses the NetworkID parameter and NetworkName parameter that you specify in this cmdlet to determine if the network is available. Not used in Get-TargetResource. .PARAMETER RunLevel Specifies the level of user rights that Task Scheduler uses to run the tasks that are associated with the principal. Defaults to 'Limited'.

Defaults to $false. .PARAMETER Hidden Indicates that the task is hidden in the Task Scheduler UI. .PARAMETER RunOnlyIfIdle Indicates that Task Scheduler runs the task only when the computer is idle. .PARAMETER IdleWaitTimeout Specifies the amount of time that Task Scheduler waits for an idle condition to occur. .PARAMETER NetworkName Specifies the name of a network profile that Task Scheduler uses to determine if the task can run. The Task Scheduler UI uses this setting for display purposes. Specify a network name if you specify the RunOnlyIfNetworkAvailable parameter. .PARAMETER DisallowStartOnRemoteAppSession Indicates that the task does not start if the task is triggered to run in a Remote Applications Integrated Locally (RAIL) session. .PARAMETER StartWhenAvailable Indicates that Task Scheduler can start the task at any time after its scheduled time has passed. .PARAMETER DontStopIfGoingOnBatteries Indicates that the task does not stop if the computer switches to battery power. .PARAMETER WakeToRun Indicates that Task Scheduler wakes the computer before it runs the task. .PARAMETER IdleDuration Specifies the amount of time that the computer must be in an idle state before Task Scheduler runs the task. .PARAMETER RestartOnIdle Indicates that Task Scheduler restarts the task when the computer cycles into an idle condition more than once. .PARAMETER DontStopOnIdleEnd Indicates that Task Scheduler does not terminate the task if the idle condition ends before the task is completed. .PARAMETER ExecutionTimeLimit Specifies the amount of time that Task Scheduler is allowed to complete the task. .PARAMETER MultipleInstances Specifies the policy that defines how Task Scheduler handles multiple instances of the task. .PARAMETER Priority Specifies the priority level of the task. Priority must be an integer from 0 (highest priority) to 10 (lowest priority). The default value is 7. Priority levels 7 and 8 are used for background tasks. Priority levels 4, 5, and 6 are used for interactive tasks. .PARAMETER RestartCount Specifies the number of times that Task Scheduler attempts to restart the task. .PARAMETER RestartInterval Specifies the amount of time that Task Scheduler attempts to restart the task. .PARAMETER RunOnlyIfNetworkAvailable Indicates that Task Scheduler runs the task only when a network is available. Task Scheduler uses the NetworkID parameter and NetworkName parameter that you specify in this cmdlet to determine if the network is available. .PARAMETER RunLevel Specifies the level of user rights that Task Scheduler uses to run the tasks that are associated with the principal. Defaults to 'Limited'. .PARAMETER LogonType Specifies the security logon method that Task Scheduler uses to run the tasks that are associated with the principal. #> function Test-TargetResource { [CmdletBinding()] [OutputType([System.Boolean])] param ( [Parameter(Mandatory = $true)] [System.String] $TaskName, [Parameter()] [System.String] $TaskPath = '\', [Parameter()] [System.String] $Description, [Parameter(Mandatory = $true)] [System.String] $ActionExecutable, [Parameter()] [System.String] $ActionArguments, [Parameter()] [System.String] $ActionWorkingPath, [Parameter(Mandatory = $true)] [System.String] [ValidateSet('Once', 'Daily', 'Weekly', 'AtStartup', 'AtLogOn')] $ScheduleType, [Parameter()] [System.String] $RepeatInterval = '00:00:00', [Parameter()] [System.DateTime] $StartTime = [System.DateTime]::Today, [Parameter()] [System.String] [ValidateSet('Present', 'Absent')] $Ensure = 'Present', [Parameter()] [System.Boolean] $Enable = $true, [Parameter()] [System.Management.Automation.PSCredential] $ExecuteAsCredential, [Parameter()] [System.UInt32] $DaysInterval = 1, [Parameter()] [System.String] $RandomDelay = '00:00:00', [Parameter()] [System.String] $RepetitionDuration = '00:00:00', [Parameter()] [System.String[]] $DaysOfWeek, [Parameter()] [System.UInt32] $WeeksInterval = 1, [Parameter()] [System.String] $User, [Parameter()] [System.Boolean] $DisallowDemandStart = $false, [Parameter()] [System.Boolean] $DisallowHardTerminate = $false, [Parameter()] [ValidateSet('AT', 'V1', 'Vista', 'Win7', 'Win8')] [System.String] $Compatibility = 'Vista', [Parameter()] [System.Boolean] $AllowStartIfOnBatteries = $false, [Parameter()] [System.Boolean] $Hidden = $false, [Parameter()] [System.Boolean] $RunOnlyIfIdle = $false, [Parameter()] [System.String] $IdleWaitTimeout = '02:00:00', [Parameter()] [System.String] $NetworkName, [Parameter()] [System.Boolean] $DisallowStartOnRemoteAppSession = $false, [Parameter()] [System.Boolean] $StartWhenAvailable = $false, [Parameter()] [System.Boolean] $DontStopIfGoingOnBatteries = $false, [Parameter()] [System.Boolean] $WakeToRun = $false, [Parameter()] [System.String] $IdleDuration = '01:00:00', [Parameter()] [System.Boolean] $RestartOnIdle = $false, [Parameter()] [System.Boolean] $DontStopOnIdleEnd = $false, [Parameter()] [System.String] $ExecutionTimeLimit = '08:00:00', [Parameter()] [ValidateSet('IgnoreNew', 'Parallel', 'Queue')] [System.String] $MultipleInstances = 'Queue', [Parameter()] [System.UInt32] $Priority = 7, [Parameter()] [System.UInt32] $RestartCount = 0, [Parameter()] [System.String] $RestartInterval = '00:00:00', [Parameter()] [System.Boolean] $RunOnlyIfNetworkAvailable = $false, [Parameter()] [ValidateSet('Limited', 'Highest')] [System.String] $RunLevel = 'Limited', [Parameter()] [ValidateSet('Group', 'Interactive', 'InteractiveOrPassword', 'None', 'Password', 'S4U', 'ServiceAccount')] [System.String] $LogonType ) $TaskPath = ConvertTo-NormalizedTaskPath -TaskPath $TaskPath #
