  MSDN says the commandline in CreateProcess() is limited to 32768 characters
  and the application name to MAX_PATH.
  A service name and service display name are limited to 256 characters.
  A registry key is limited to 255 characters.
  A registry value is limited to 16383 characters.
  Therefore we limit the service name to accommodate the path under HKLM.
