Finding Service Privileges

by Apr 24, 2019

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
    # 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."
    # read the service privileges from registry
    $Path = 'HKLM:\SYSTEM\CurrentControlSet\Services\' +  $service.Name
    $Privs = Get-ItemProperty -Path $Path -Name RequiredPrivileges

    # output in custom object
        ServiceName = $Service.Name
        DisplayName = $Service.DisplayName
        Privileges = $privs.RequiredPrivileges
PS C:\> Get-ServicePrivilege spooler
