This topic describes the parameters that are valid on all Windows
    PowerShell workflow commands. Because the Windows PowerShell engine
    adds them to workflows, you can use these parameters on any workflow
    and they are automatically enabled on the workflows that you author.

    Windows PowerShell Workflow common parameters are a set of cmdlet 
    parameters that you can use with all Windows PowerShell workflows
    and activities. They are added by the Windows PowerShell Workflow
    engine, not by the workflow author, and they are automatically
    available on every workflow and activity. 

    All workflow parameters are optional and named (not positional). 
    They do not take input from the pipeline.

    Most of the workflow common parameters have a PS prefix, such as 
    PSComputerName and PSCredential. The PS-prefixed parameters configure
    the connection and the execution environment for the target computers,
    also known as "remote nodes."

    Many of the workflow common parameters, such as PSAllowRedirection and
    AsJob, have names that are similar to parameters used in Windows PowerShell
    remoting and background jobs. These parameters work in the same way as
    the similarly-named remoting and job parameters, so you can use the
    knowledge that you developed in remoting and jobs to manage workflows.   

    Workflows are introduced in Windows PowerShell 3.0. 
  This section describes the workflow common parameters.

        Runs the workflow as a workflow job. The workflow command 
        immediately returns an object that represents a parent job. The 
        parent job contains the child jobs that are running on each of 
        the target computers. To manage the job, use the Job
        cmdlets. To get the job results, use the Receive-Job cmdlet

        Specifies a friendly name for the workflow job. By default, jobs are
        named "Job", where  is an ordinal number. 

        If you use the JobName parameter in a workflow command, the workflow is run
        as a job and the workflow command returns a job object, even if you do not
        include the AsJob parameter in the command.

        For more information about Windows PowerShell background jobs, see
        about_Jobs (http://go.microsoft.com/fwlink/?LinkID=113251).

        Allows redirection of the connection to the target computers.

        When you use the PSConnectionURI parameter, the remote destination can
        return an instruction to redirect to a different URI. By default, Windows
        PowerShell does not redirect connections, but you can use the
        PSAllowRedirection parameter to allow redirection of the connection to the
        target computer.

        You can also limit the number of times that the connection is redirected by
        setting the MaximumConnectionRedirectionCount property of the
        $PSSessionOption preference variable, or the
        MaximumConnectionRedirectionCount property of the value of the
        PSSessionOption parameter. The default value is 5. For more information,
        see the description of the PSSessionOption parameter and 
        the New-PSSessionOption cmdlet

        Specifies the application name segment of the connection URI that is used
        to connect to the target computers. Use this parameter to specify the
        application name when you are not using the ConnectionURI parameter in the

        The default value is the value of the $PSSessionApplicationName preference
        variable on the local computer. If this preference variable is not defined,
        the default value is WSMAN. This value is appropriate for most uses. For
        more information, see about_Preference_Variables 

        The WinRM service uses the application name to select a listener to service
        the connection request. The value of this parameter should match the value 
        of the URLPrefix property of a listener on the remote computer.

        Specifies the mechanism that is used to authenticate the user's credentials
        when connecting to the target computers. Valid values are Default, Basic,
        Credssp, Digest, Kerberos, Negotiate, and NegotiateWithImplicitCredential.
        The default value is Default.

        For information about the values of this parameter, see the description of
        the System.Management.Automation.Runspaces.AuthenticationMechanism
        enumeration in MSDN.

       CAUTION: Credential Security Service Provider (CredSSP) authentication, in
       which the user's credentials are passed to a remote computer to be
       authenticated, is designed for commands that require authentication on more
       than one resource, such as accessing a remote network share. This mechanism
       increases the security risk of the remote operation. If the remote computer
       is compromised, the credentials that are passed to it can be used to control
       the network session.

        Specifies the authentication level for the connections to
        the target computers. The default value is Default.

        Valid values are:

        Unchanged:       The authentication level is the same as the previous
        Default:         Windows Authentication.
        None:            No COM authentication.
        Connect:         Connect-level COM authentication.
        Call:            Call-level COM authentication.
        Packet:          Packet-level COM authentication.
        PacketIntegrity: Packet Integrity-level COM authentication.
        PacketPrivacy:   Packet Privacy-level COM authentication.

        Specifies the digital public key certificate (X509) of a user account that
        has permission to perform this action. Enter the certificate thumbprint of
        the certificate. 

        Certificates are used in client certificate-based authentication. They can 
        only be mapped to local user accounts; they do not work with domain 

        To get a certificate, use the Get-Item 
        (http://go.microsoft.com/fwlink/?LinkID=113319) or 
        Get-ChildItem (http://go.microsoft.com/fwlink/?LinkID=113308) cmdlets
        in the Windows PowerShell Cert: drive.

        Specifies the list of computers that are the target nodes of the workflow.
        Commands or activities in a workflow are run on the computers that are 
        specified by using this parameter. The default is the local computer.

        Type the NETBIOS name, IP address, or fully-qualified domain name of one or
        more computers in a comma-separated list. To specify the local computer,
        type the computer name, "localhost", or a dot (.).         

        To include the local computer in the value of the PSComputerName parameter,
        open Windows PowerShell with the "Run as administrator" option.

        If this parameter is omitted from the command, or it value is $null or an
        empty string, the workflow target is the local computer and Windows
        PowerShell remoting is not used to run the command.
        To use an IP address in the value of the ComputerName parameter, the
        command must include the PSCredential parameter. Also, the computer must be
        configured for HTTPS transport or the IP address of the remote computer
        must be included in the WinRM TrustedHosts list on the local computer. For
        instructions for adding a computer name to the TrustedHosts list, see "How 
        to Add a Computer to the Trusted Host List" in about_Remote_Troubleshooting

        Specifies the session configurations that are used to configure sessions on
        the target computers. Enter a session configuration on the target computers
        (not the workflow server computer). The default is

        Specifies the maximum number of attempts to connect to each target computer
        if the first connection attempt fails. Enter a number between 1 and
        4,294,967,295 (UInt.MaxValue). The default value, zero (0), represents no
        retry attempts.

        Specifies the delay between connection retry attempts in seconds. The
        default value is zero (0). This parameter is valid only when the value of
        PSConnectionRetryCount is at least 1.

        Specifies a Uniform Resource Identifier (URI) that defines the connection
        endpoint for the workflow on the target computer. The URI must be fully 

        The format of this string is as follows: 


        The default value is http://localhost:5985/WSMAN.

        If you do not specify a PSConnectionURI, you can use the PSUseSSL,
        PSComputerName, PSPort, and PSApplicationName parameters to specify the
        PSConnectionURI values. 

        Valid values for the Transport segment of the URI are HTTP and HTTPS. If
        you specify a connection URI with a Transport segment, but do not specify a
        port, the session is created with standards ports: 80 for HTTP and 443 for
        HTTPS. To use the default ports for Windows PowerShell remoting, specify 
        port 5985 for HTTP or 5986 for HTTPS. 

        Specifies a user account that has permission to run a workflow on the
        target computer. The default is the current user. This parameter is valid
        only when the PSComputerName parameter is included in the command.

        Type a user name, such as "User01" or "Domain01\User01", or enter a 
        variable that contains a PSCredential object, such as one that the
        Get-Credential cmdlet returns. If you enter only a user name, you will be
        prompted for a password.

        Determines how long the workflow and all related resources are maintained
        in the system. When the timeout expires, the workflow is deleted, even if 
        it is still processing. Enter a value between 10 and 4,294,967,295. The
        default value, 0 (zero), means that there is no elapsed timeout.  

        Specifies different workflow common parameter values for different target

        Enter a comma-separated list of hash tables with one hash table for each
        target computer. In each hash table, the first key is PSComputerName and
        its value is the name of the target computer. Wildcard characters are
        permitted in the computer name. For the remaining keys in the hash table,
        the key is the parameter name and the value is the parameter value.

        For example:
          -PSParameterCollection @{PSComputerName="Server01";
              PSElapsedTimeoutSec=10; PSConnectionRetryCount=6}, 
              @{PSComputerName="*"; PSElapsedTimeoutSec=20}

         Adds checkpoints to the workflow, in addition to any 
         checkpoints that are specified in the workflow. 

         This parameter cannot suppress the checkpoints
         in a workflow, such as those specified by using the 
         PSPersist activity common parameter, the Checkpoint-Workflow
         activity, or the $PSPersistPreference variable. 

         A "checkpoint" or "persistence point" is a snapshot of the 
         workflow state and data that is captured while the workflow
         runs and is saved to a persistence store on disk or in a SQL
         database. Windows PowerShell Workflow uses the saved data to 
         resume a suspended or interrupted workflow from the last 
         persistence point, rather than to restart the workflow.

         Valid values:

        --  (Default) If you omit this parameter, a checkpoint is 
            added to the beginning and end of the workflow, in addition
            to any checkpoints that are specified in the workflow.
         -- $True. Adds a checkpoint to the beginning and end of the 
            workflow and a checkpoint after each activity, in addition
            to any checkpoints that are specified in the workflow.

         -- $False. No checkpoints are added. Checkpoints are taken 
            only when specified in the workflow.

        Specifies the network port on the target computers. The default ports are
        5985 (the WinRM port for HTTP) and 5986 (the WinRM port for HTTPS). 

        Do not use the PSPort parameter unless you must. The port set in the
        command applies to all computers or sessions on which the command runs. An
        alternate port setting might prevent the command from running on all
        computers. Before using an alternate port, you must configure the WinRM
        listener on the remote computer to listen at that port. 

        Provides customized information to workflow jobs. Enter a hash table.
        The keys and values are customized for each workflow. For information
        about the private metadata of a workflow, see the help topic for the

        This parameter is not processed by the Windows PowerShell Workflow
        engine. Instead, the engine passes the hash table directly to the

        Specifies the running time of the workflow in seconds, excluding any
        time that the workflow is suspended. If workflow execution is not
        complete when the time expires, the Windows PowerShell Workflow engine
        forcibly stops the execution of the workflow.

        Sets advanced options for the sessions to the target computers. Enter
        a PSSessionOption object, such as one that you create by using the
        New-PSSessionOption cmdlet.

        The default values for the session options are determined by the value
        of the $PSSessionOption preference variable, if it is set. Otherwise, the
        session uses the values specified in the session configuration.

       For a description of the session options, including the default values,
       see the help topic for the New-PSSessionOption cmdlet 
       (http://go.microsoft.com/fwlink/?LinkID=144305). For information about the        $PSSessionOption preference variable, see about_Preference_Variables 

        Uses the Secure Sockets Layer (SSL) protocol to establish a connection
        to the target computer. By default, SSL is not used.

        WS-Management encrypts all Windows PowerShell content transmitted over
        the network. UseSSL is an additional protection that sends the data
        across an HTTPS, instead of HTTP. If you use this parameter, but SSL
        is not available on the port used for the command, the command fails.
