Windows PowerShell command on Get-command Save-NetGPO

NAME
    Save-NetGPO
    
SYNOPSIS
    Applies the modified cached local Group Policy Object (GPO) to the actual GPO.
    
    
SYNTAX
    Save-NetGPO [-GPOSession]  [-AsJob] [-CimSession ] [-ThrottleLimit ] 
    []
    
    
DESCRIPTION
    The Save-NetGPO cmdlet saves the changes made to the local cached group policy object. The cached Group Policy 
    Object (GPO) copy is created with the Open-NetGPO cmdlet.
    
    Individual operations on group policy objects require a round-trip to load the policy store. When the policy store 
    is a GPO on a busy domain controller, an administrator will want to open the GPO, do the work on it, and then save 
    it back, with an in-memory copy.
    
    Modifications are performed through the use of the GPOSession parameter.
    
    Note: This cmdlet does not batch individual changes, it loads and saves the entire GPO at once. If any other 
    changes were made by another administrator, or in a different Windows PowerShellr session, saving the GPO would 
    overwrite those changes.
    

PARAMETERS
    -AsJob []
        Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. 
         The cmdlet immediately returns an object that represents the job and then displays the command prompt. You 
        can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get 
        the job results, use the Receive-Job cmdlet. 
         For more information about Windows PowerShellr background jobs, see about_Jobs.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    -CimSession 
        Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such 
        as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local 
        computer.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    -GPOSession 
        Specifies the GPO session to be saved. 
                                 
        This parameter is used in the same way as the PolicyStore parameter. When modifying GPOs in Windows 
        PowerShellr, each change to a GPO requires the entire GPO to be loaded, modified, and saved back. On a busy 
        Domain Controller (DC), this can be a slow and resource-heavy operation. A GPO session loads a domain GPO onto 
        the local computer and makes all changes in a batch, before saving it back. This reduces the load on the DC 
        and speeds up the Windows PowerShell cmdlets. To load a GPO Session, use the Open-NetGPO cmdlet. To save a GPO 
        Session, use this cmdlet.
        
        Required?                    true
        Position?                    1
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    -ThrottleLimit 
        Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this 
        parameter is omitted or a value of 0 is entered, then Windows PowerShellr calculates an optimum throttle limit 
        for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies 
        only to the current cmdlet, not to the session or to the computer.
        
        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        
    
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer, PipelineVariable, and OutVariable. For more information, see 
        about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216). 
    
INPUTS
        Microsoft.Management.Infrastructure.CimInstance#root\StandardCimv2\GPOSession
    
        The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management 
        Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the 
        underlying WMI object.
    
    
OUTPUTS
        None
    
        
    
    
    EXAMPLE 1
    
    PS C:\>$gpoSession = Open-NetGPO -PolicyStore castle.contoso.com\Win8ClientFirewallPolicy
    
    
    
    PS C:\>Remove-NetFirewallRule -Name BlockIMAccess -GPOSession $gpoSession
    
    
    
    PS C:\>New-NetFirewallRule -Name LimitIMAccess -DisplayName "Contoso Messenger" -Program 
    "%ProgramFiles(X86)%\Contoso Messenger\cmsg.exe" -Action Block -GPOSession $gpoSession
    
    
    
    PS C:\>Save-NetGPO -GPOSession $gpoSession
    
    This example replaces one rule in a domain GPO with another using a cached copy of the GPO.
