i'm a typical gamer, internet browser with broadband w/o ADSL and the services I disable are: Alerter - manual Automatic Updates (ewwwww) - disabled Error Reporting Service - manual Help and Support - manual IPSEC - manual Machine Debug Manager ( The mdm thing from office ) - manual Messenger - manual ( This is not MSN messenger ) Portable Media Serial Number Service - manual Protected Storage - manual Remote Registry - manual Wireless Zero Configuration - manual I think that's about it. Hope this helps
