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.

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

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

Required? false
Position? named
Default value none
Accept pipeline input? true(ByPropertyName)
Accept wildcard characters? false
