Microsoft WDS reference: Copies install images within an image group. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Copy-WdsInstallImage. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.
-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.
-ClientCount
Specifies the number of clients that must connect to a transmission. If you also specify *MulticastTransmission*, this parameter specifies the number of clients that must connect to the ScheduledCast transmission for it to start. The *StartScheduledCast* parameter can start a transmission before reaching the client count. If you specify the *ClientCount* parameter with the *StartTime* parameter, the transmission starts when either a sufficient number of clients connect, or at the time specified by the *StartTime* parameter. You may not use this parameter together with the *ManualStart* parameter.
-FileName
Specifies a file name. This is the file name of the install image. Use this parameter to specify the file name for the install image if the install image name does not uniquely identify the image.
-ImageGroup
Specifies the name of an image group. This image group contains the image to copy. If you do not specify an image group, and only one image group exists on the server, that image group will be used by default. If more than one image group exists on the server, you must specify an image group.
-ImageName (required)
Specifies the name of an image. This is the name of the image to copy. You must provide a new image name.
-ManualStart (required)
Indicates that the transmission uses a manual start. If you also specify the *MulticastTransmission* parameter with this parameter, the cmdlet creates a ScheduledCast transmission that does not start until a StartScheduledCast command is given.
-Multicast (required)
Indicates that the cmdlet enables an AutoCast transmission on the image. If you do not specify a name by using the *TransmissionName* parameter, the multicast transmission uses the image name.
-NewDescription
Specifies a new description for the install image to create in the copy operation.
-NewFileName (required)
Specifies a new name for the image file to create in the copy operation.
-NewImageName (required)
Specifies a new name for the image to create in the copy operation.
-StartTime
Specifies a day and time, in MM/DD/YYYY.hh:mm:ss format, that denotes the start time. When you specify the *MulticastTransmission* parameter, this parameter denotes the time the ScheduledCast transmission starts. The StartScheduledCast command can start a transmission before reaching the client count. If you specify both the *StartTime* parameter and the *ClientCount* parameter, the transmission starts when either a sufficient number of clients connect, or the time specified in this parameter is reached. Do not specify this parameter together with the *ManualStart* parameter.
-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.
-TransmissionName
Specifies a name for the multicast transmission.
Prerequisites
Windows with the WDS module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
