Get-Service can provide basic information about Windows services but won’t list the required privileges. Here is a small PowerShell function that accepts a service name and returns the service privileges:
function Get-ServicePrivilege { param ( [Parameter(Mandatory)] [string] $ServiceName ) # find the service $Service = @(Get-Service -Name $ServiceName -ErrorAction Silent) # bail out if there is no such service if ($Service.Count -ne 1) { Write-Warning "$ServiceName unknown." return } # read the service privileges from registry $Path = 'HKLM:\SYSTEM\CurrentControlSet\Services\' + $service.Name $Privs = Get-ItemProperty -Path $Path -Name RequiredPrivileges # output in custom object [PSCustomObject]@{ ServiceName = $Service.Name DisplayName = $Service.DisplayName Privileges = $privs.RequiredPrivileges } }
