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 WindowsÿUpdate (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 Windowsr 8 or Windows Serverr 2012.
    

PARAMETERS
    -CheckHealth []
        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 []
        Prevents DISM from contacting WindowsUpdate (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 Windowsr 8, Windows Serverr 2012, 
        or Windowsr Preinstallation Environment (Windows PE) 4.0.
        
        Required?                    false
        Position?                    named
        Default value                none
        Accept pipeline input?       true(ByPropertyName)
        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
        
        Required?                    false
        Position?                    named
        Default value                none
        Accept pipeline input?       true(ByPropertyName)
        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.
        
        Required?                    false
        Position?                    named
        Default value                none
        Accept pipeline input?       true(ByPropertyName)
        Accept wildcard characters?  false
        
    -NoRestart []
        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 
        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 
        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 []
        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 []
        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 []
        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 []
        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. WindowsUpdate (WU) is also 
        used for online images.
        
        Source can only be used when servicing images that are running at least Windowsr 8 or Windows Serverr 2012.
        
        Required?                    false
        Position?                    named
        Default value                none
        Accept pipeline input?       true(ByPropertyName)
        Accept wildcard characters?  false
        
    -SystemDrive []
        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 []
        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
