NAME Dismount-WindowsImage
SYNOPSIS
Dismounts a Windows image from the directory it is mapped to.
SYNTAX
Dismount-WindowsImage [-Append] [-CheckIntegrity] [-LogLevel {Errors | Warnings | WarningsInfo}] [-LogPath <String>] [-ScratchDirectory <String>]
-Path <String> -Save [<CommonParameters>]
Dismount-WindowsImage [-LogLevel {Errors | Warnings | WarningsInfo}] [-LogPath <String>] [-ScratchDirectory <String>] -Discard -Path <String>
[<CommonParameters>]
DESCRIPTION
The Dismount-WindowsImage cmdlet either saves or discards the changes to a Windows image and then dismounts the image.
The Path parameter specifies the location of the mounted Windows image.
The Append parameter specifies the location of an existing .wim file to add the Windows image to when you dismount it instead of overwriting the
existing image.
The CheckIntegrity parameter detects and tracks .wim file corruption. CheckIntegrity stops the operation if DISM detects that the .wim file is
corrupted when used with the Mount-WindowsImage cmdlet.
The CheckIntegrity and Append parameters do not apply to virtual hard disk (VHD) files.
PARAMETERS
-Append [<SwitchParameter>]
Specifies the location of an existing .wim file to add the Windows image to when you dismount it instead of overwriting the existing image.
Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-CheckIntegrity [<SwitchParameter>]
Detects and tracks .wim file corruption. CheckIntegrity stops the operation if DISM detects that the .wim file is corrupted when used with the
Mount-WindowsImage cmdlet.
Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-Discard <SwitchParameter>
Discards the changes to a Windows image.
Required? true
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-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 only
2 = Errors and warnings
3 = Errors, warnings, and information
4 = All of the information listed previously, plus debug output
Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-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.
Required? true
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-Save <SwitchParameter>
Saves the changes to a Windows image.
Required? true
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).
INPUTS
System.String[]
Microsoft.Dism.Commands.ImageObject
Microsoft.Dism.Commands.MountedImageInfoObject
Microsoft.Dism.Commands.ImageInfoObject
OUTPUTS
Microsoft.Dism.Commands.BaseDismObject
Example 1: Dismount an operating system image
PS C:\\>Dismount-WindowsImage ????????Path "c:\\offline" -Save
This command dismounts the Windows Image mapped to c:\\offline and saves any changes that were made while servicing the image.
