DESCRIPTION

The Repair-WindowsImage cmdlet repairs a Windows image in a WIM or VHD file.



Use the Online parameter to specify the running operating system on your local computer, or use the Path parameter to specify the location of a

mounted Windows image.



The LimitAccess parameter prevents access to Windows?? Update (WU) as a Source for repairing online images.



The CheckHealth parameter checks whether the image has been flagged as corrupted by a failed process and whether the corruption can be repaired.



The ScanHealth parameter scans the image for component store corruption. This operation will take several minutes.



The RestoreHealth parameter scans the image for component store corruption, and then performs repair operations automatically. This operation will

take several minutes.



The Source parameter specifies the location of known good versions of files that can be used for the repair, such as a path to the root directory

of a mounted image.



CheckHealth, ScanHealth, RestoreHealth, Source, and LimitAccess can only be used when servicing images that are running at least Windows???? 8 or

Windows Server???? 2012.





PARAMETERS

-CheckHealth [<SwitchParameter>]

Checks whether the image has been flagged as corrupted by a failed process and whether the corruption can be repaired.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false



-LimitAccess [<SwitchParameter>]

Prevents DISM from contacting Windows?? Update (WU) when searching for the source files to repair an online image.



LimitAccess can only be used when servicing images that are running at least Windows???? 8, Windows Server???? 2012, or Windows???? Preinstallation

Environment (Windows PE) 4.0.



Required? false

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



-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.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false



-Online <SwitchParameter>

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



Required? true

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



-RestoreHealth [<SwitchParameter>]

Scans the image for component store corruption, and then performs repair operations automatically. This operation will take several minutes.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false



-ScanHealth [<SwitchParameter>]

Scans the image for component store corruption. This operation will take several minutes.



Required? false

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



-Source [<String[]>]

Specifies the location of the files that are required to repair an image. You can specify the Windows directory of a mounted image or a

running Windows installation that is shared on the network.



If you specify multiple Source arguments, the files are gathered from the first location where they are found and the rest of the locations

are ignored. Separate source locations with a comma.



If you do not specify a Source, the default location set by Group Policy is used. Windows?? Update (WU) is also used for online images.



Source can only be used when servicing images that are running at least Windows???? 8 or Windows Server???? 2012.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value none

Accept pipeline input? true(ByPropertyName)

Accept wildcard characters? false
