[<CommonParameters>] 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 1This 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" -VerifyThis 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 |
