Detailed Description

The Enable-WindowsOptionalFeature cmdlet enables or restores an optional feature in a Windows image.

Use the Online parameter to specify the running operating system on your local computer, or use the Path parameter to specify the location of a mounted Windows image.

The PackageName parameter specifies the package that the feature is a component of. This parameter is optional when the package is the Windows Foundation package.

The FeatureName parameter specifies the feature to add. You can specify more than one feature in the same package. Separate feature names with a comma.

The Source parameter specifies the location of files that are needed to restore a removed feature.

The LimitAccess parameter prevents access to Windows Update (WU) as a Source for restoring features to online images. The All parameter enables all parent features of the specified feature before enabling the specified feature. The parent feature will be enabled with default values.

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.

Prevents DISM from contacting Windows Update (WU) when searching for the source files to restore a feature on an online image.

LimitAccess can only be used when servicing Windows 8, Windows Server® 2012, Windows® Preinstallation Environment (Windows PE) 4.0 images.

-LogPath<String>

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.

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.

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 (WU) is also used for online images.

Source can only be used when servicing Windows 8 or Windows Server® 2012 images.
