        This module will query the system for services and display name and
        configuration info for each returned service. It allows you to
        optionally search the credentials, path, or start type for a string
        and only return the results that match. These query operations are
        cumulative and if no query strings are specified, it just returns all
        services.  NOTE: If the script hangs, windows firewall is most likely
        on and you did not migrate to a safe process (explorer.exe for
        example).
