# Analysis Tip: Several services keys have Parameters subkeys that point to
# the ServiceDll value; During intrusions, a service key may be added to
# the system's Registry; this module provides a quick look, displaying the
# Service names (in malware, sometimes random) and the ServiceDll value,
# sorted based on the LastWrite time of the <service name>\Parameters subkey.
