Microsoft Dism reference: Applies an image to a specified location. 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 Expand-WindowsImage. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-ApplyPath (required)
Specifies the location where the image is to be applied.
-CheckIntegrity
Detects and tracks .wim file corruption when used with the Add-WindowsImage, Dismount-WindowsImage, or Save-WindowsImage cmdlet. CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with the Expand-WindowsImage or Mount-WindowsImage cmdlet.
-Compact
Indicates that this cmdlet applies the operating system image to the specified drive with individual operating system files compressed. If you do not specify this parameter, this cmdlet lays down all of the files in the image without compression.
-ConfirmTrustedFile
Specifies that this cmdlet validates the image for Trusted Desktop on Windows 8 or Windows 8.1. This option can only be run on a computer running at least Windows Preinstallation Environment (Windows PE) 4.0.
-ImagePath (required)
Specifies the location of a WIM file.
-Index (required)
Specifies the index number of a Windows image in a WIM or VHD file. For a VHD file, the Index must be 1.
-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.
-Name (required)
Specifies the name of an image in a WIM file.
-NoRpFix
Disables the reparse point tag fix. A reparse point is a file that contains a link to another file on the file system. If the parameter is not specified, reparse points that resolve to paths outside of the value specified by the *ImagePath* parameter will not be captured.
-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.
-SplitImageFilePattern
Specifies the location and name of the base split image file.
-SupportEa
Applies an image with extended attributes.
-Verify
Checks for errors and file duplication. During an apply operation, for example, using the Add-WindowsImage cmdlet, the size and the hash of the file being applied are checked against the image file to verify they are both equal. During a capture operation, for example, when using the New-WindowsImage cmdlet, after the files is captured into a Windows image, the file is written to a temporary file and compared on a bit-by-bit basis with the original file.
-WIMBoot
Specifies that the offline image to be added will be formatted to install on a Windows Image Format Boot (WIMBoot) system.
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.
