There are quite a few services you can disable from starting automatically. This would be to speed up your boot time and free resources.

Some possibilities are: Alerter Application Management Clipbook Fast UserSwitching Human Interface Devices Indexing Service Messenger Net Logon NetMeeting QOS RSVP Remote Desktop Help Session Manager Remote Registry Routing & Remote Access SSDP Discovery Service Universal Plug and Play Device Host Web Client
