Description

The Expand-WindowsImage cmdlet applies an image to a specified location.

This cmdlet does not apply to virtual hard disk (VHD) files.

Examples

Example 1: Apply an image in a file to a partion

PS C:\> Expand-WindowsImage -ImagePath "c:\imagestore\custom.wim" -ApplyPath "d:\" -Index 1

This command applies an image at index 1 in the c:\imagestore\custom.wim file to partition d:.

Example 2: Apply a split image

PS C:\> Expand-WindowsImage -ImagePath "c:\imagestore\split\custom.swm" -SplitImageFilePattern "c:\imagestore\split\custom*.swm" -ApplyPath "d:\" -Name "Windows Pro" -Verify

This command applies the split image with a name that matches c:\imagestore\split\custom*.swm with a name of Windows Pro to partition d:. Check for errors and file duplication while applying the image.

Parameters

-ApplyPath

Specifies the location where the image is to be applied.

Type:	String
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ImagePath

Specifies the location of a WIM file.

Type:	String
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Index

Specifies the index number of a Windows image in a WIM or VHD file. For a VHD file, the Index must be 1.

Type:	UInt32
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-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

Type:	LogLevel
Aliases:	LL
Accepted values:	Errors, Warnings, WarningsInfo
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	String
Aliases:	LP
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies the name of an image in a WIM file.

Type:	String
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-SplitImageFilePattern

Specifies the location and name of the base split image file.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-SupportEa

Applies an image with extended attributes.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-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.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-WIMBoot

Specifies that the offline image to be added will be formatted to install on a Windows Image Format Boot (WIMBoot) system.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
