Dism

The Deployment Image Servicing and Management (DISM) platform is used to mount and service Windows images before deployment. A subset of DISM commands can be used on online Windows images. You can use DISM tools to mount, and get information about, Windows image (.wim) files or virtual hard disks (.vhd or .vhdx). You can also use it to install, uninstall, configure, and update Windows features, packages, and drivers in a Windows image or to change the edition of a Windows image.

The DISM platform also includes a command-line tool, dism.exe, and the DISM API. The command-line tool is available in the Windows Assessment and Deployment Kit (Windows ADK) and includes additional functionality that supports servicing commands for international settings.

You can check for errors when running Dism cmdlets by checking if the $?. If set to True, the last operation succeeded. If False, the last operation failed. The $LASTEXITCODE contains the exit code of the last Win32 executable run. For example, to check that the Get-WindowsImage cmdlet fails to get information about the Windows image contained in the file, E:\images\c.wim, type the following:

try
{

    Get-WindowsImage -ImagePath E:\images\c.wim
}
catch
{
    $message = "TRAPPED: {0}: '{1}'" -f ($_.Exception.GetType().FullName), ($_.Exception.Message)
    Write-host $message
}
