The `Disable-AclInheritnace` function disables inheritance, removing all inherited permissions. You can optionally preserve the currently inherited permission as explicit permissions using the `-Preserve` switch. This function is paired with `Enable-AclInheritance`. Beginning in Carbon 2.4, this function will only disable inheritance if it is currently enabled. In previous versions, it always disabled inheritance. .LINK Disable-AclInheritance .LINK Get-Permission .LINK Grant-Permission .LINK Revoke-Permission .EXAMPLE Disable-AclInheritance -Path C:\Projects\Carbon Removes all inherited access rules from the `C:\Projects\Carbon` directory. Non-inherited rules are preserved. .EXAMPLE Disable-AclInheritance -Path hklm:\Software\Carbon -Preserve Stops `HKLM:\Software\Carbon` from inheriting acces rules from its parent, but preserves the existing, inheritied access rules. #> [CmdletBinding(SupportsShouldProcess=$true)] param( [Parameter(Mandatory=$true,ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$true)] [Alias('PSPath')] [string] # The file system or registry path whose access rule should stop inheriting from its parent. $Path, [Switch] # Keep the inherited access rules on this item. $Preserve ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState $acl = Get-Acl -Path $Path if( -not $acl.AreAccessRulesProtected ) { Write-Verbose -Message ("[{0}] Disabling access rule inheritance." -f $Path) $acl.SetAccessRuleProtection( $true, $Preserve ) $acl | Set-Acl -Path $Path } } Set-Alias -Name 'Unprotect-AclAccessRules' -Value 'Disable-AclInheritance' Set-Alias -Name 'Protect-Acl' -Value 'Disable-AclInheritance' |
