Add-WindowsPackage [-IgnoreCheck] [-LogLevel {Errors | Warnings | WarningsInfo}] [-LogPath <String>] [-NoRestart][-PreventPending] [-ScratchDirectory <String>] [-SystemDrive <String>] [-WindowsDirectory <String>] -PackagePath*<String> -Path* <String> [<CommonParameters>]

The Add-WindowsPackage cmdlet installs a specified .cab or .msu package in the image.


-IgnoreCheck [<SwitchParameter>]

Skips the applicability check for each package.

-LogLevel [<LogLevel>]

Specifies the maximum output level shown in the logs. The default log level is 3. The accepted values are as follows:1 = Errors only2 = Errors and warnings3 = Errors, warnings, and information4 = All of the information listed previously, plus debug output

-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.

-NoRestart [<SwitchParameter>]

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 <SwitchParameter>

Specifies that the action is to be taken on the operating system that is currently running on the local computer.

-PackagePath <String>

Specifies the location of the package to add to the image.

Valid values are:

--A single .cab or .msu file.

--A folder that contains a single expanded .cab file.

--A folder that contains a single .msu file.

--A folder that contains multiple .cab or .msu files.

If PackagePath is a folder that contains a .cab or .msu files at its root, any subfolders will also be recursively checked for .cab and .msu files.

-Path <String>

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.

-PreventPending [<SwitchParameter>]

Skips the installation of the package if the package or Windows image has pending online actions.

-ScratchDirectory [<String>]

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.

-SystemDrive [<String>]

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 [<String>]

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.


This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.
