Ever wonder just what those 'services' are that Windows XP runs in the background? Well Black Viper's got a ton of info for you on both XP as well as Win2K's services and tells you exactly those services are doing and gives you suggestions on different configurations. Black Viper has recently updated his listings, with more explanations and a new section on some mystery services that you might have been curious about. Take my advice though and take your time to examine each service that you may want to alter or make a list of the ones that you do, so that you can go back and set it back to a default setting if something gets upset.
