Microsoft Dism reference: Enables a feature in a Windows image. 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 Enable-WindowsOptionalFeature. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-All
Enables all parent features of the specified feature. If a parent feature is required for the specified feature to be enabled in the image, *All* will enable the parent and all of its default dependencies.
-FeatureName (required)
Specifies the name of the feature to be enabled. Feature names are case sensitive if you are servicing a Windows image running a version of Windows earlier than Windows® 8. You can use Get-WindowsOptionalFeature to find the name of the feature in the image.
-LimitAccess
Prevents DISM from contacting Windows Update when searching for the source files to restore a feature on an online image. LimitAccess can only be used when servicing images with Windows 8, Windows Server® 2012, Windows® Preinstallation Environment (Windows PE) 4.0 or a later version.
-LogLevel
Specifies the maximum output level shown in the logs. The default log level is 3. The accepted values are as follows: - 1 = Errors only - 2 = Errors and warnings - 3 = Errors, warnings, and information - 4 = All of the information listed previously, plus debug output
-LogPath
Specifies the full path and file name to log to. If not set, the default is %WINDIR%\Logs\Dism\dism.log. In Windows PE, the default directory is the RAMDISK scratch space which can be as low as 32 MB. The log file will automatically be archived. The archived log file will be saved with .bak appended to the file name and a new log file will be generated. Each time the log file is archived the .bak file will be overwritten. When using a network share that is not joined to a domain, use the net use command together with domain credentials to set access permissions before you set the log path for the DISM log.
-NoRestart
Suppresses reboot. If a reboot is not required, this command does nothing. This option will keep the application from prompting for a restart or keep it from restarting automatically.
-Online (required)
Specifies that the action is to be taken on the operating system that is currently running on the local computer.
-PackageName
Specifies the name of a package in the Windows image.
-Path (required)
Specifies the full path to the root directory of the offline Windows image that you will service. If the directory named Windows is not a subdirectory of the root directory, *WindowsDirectory* must be specified.
-ScratchDirectory
Specifies a temporary directory that will be used when extracting files for use during servicing. The directory must exist locally. If not specified, the \Windows\%Temp% directory will be used, with a subdirectory name of a randomly generated hexadecimal value for each run of DISM. Items in the scratch directory are deleted after each operation. You should not use a network share location as a scratch directory to expand a package (.cab or .msu file) for installation. The directory used for extracting files for temporary usage during servicing should be a local directory.
-Source
Specifies the location of the files that are required to restore a feature that has been removed from the image. You can specify the Windows directory of a mounted image or a running Windows installation that is shared on the network. If you specify multiple *Source* arguments, the files are gathered from the first location where they are found and the rest of the locations are ignored. Separate feature names with a comma. If you do not specify a *Source* for a feature that has been removed, the default location set by Group Policy is used. Windows Update is also used for online images. *Source* can only be used when servicing an image with Windows 8 or Windows Server 2012 or a later version.
-SystemDrive
Specifies the path to the location of the BootMgr files. This is necessary only when the BootMgr files are located on a partition other than the one that you are running the command from. Use -SystemDrive to service an installed Windows image from a Windows PE environment.
-WindowsDirectory
Specifies the path to the Windows directory relative to the image path. This cannot be the full path to the Windows directory; it should be a relative path. If not specified, the default is the Windows directory in the root of the offline image directory.
Prerequisites
Windows with the Dism 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.
