Services dependent on this being started: Alerter, Messenger, and Net Logon.Before changing any of the defaults - use the links above to find what exactly theservice does. The Elder Geek also has some good advice about services.It is inadvisable to disable a service without being aware of the consequences, alwaysstart by setting the service to manual, reboot and test for any problems.A service set to manual may be automatically restarted if another service is dependenton it.A service set to disabled will not restart even if its required to boot the machine!Stopping or disabling a service will generally save a small amount of memory and willreduce the number of software interrupts (cpu message queue.) The main reason fortinkering with services is to harden the system against security vulnerabilities. Disableeverything that you dont need or use - then any future problems with those servicescannot affect the machine.To document all the services currently installed:SC QUERY state= all |findstr "DISPLAY_NAME STATE">my_services.csvSome XP services communicate and send data directly to Microsoft, this is notgenerally something to lose sleep over. Managing the running of these services may bea consideration if confidentiality/anonymity is highly important to you.Removing a service completely
To delete a service, you may be tempted to hack the registry settings under(HKLM/SYSTEM/CurrentControlSet/Services) this is not a reliable or recommendedmethod, far better is to use the SC command:SC delete NameofServiceTodeleteEnable or Disable PortsMany services and applications rely on the use of a specific PORT - to determine if aparticular port is enabled for use, review the list of Service names and port numbersheld in the "services" file (windowssystem32driversetcservices)Installing a good firewall is the easiest way to manage this."The service we render to others is really the rent we pay for our room on this earth. It isobvious that man is himself a traveler; that the purpose of this world is not to have andto hold but to give and serve. There can be no other meaning." - Sir Wilfred T.
