Any agent that runs as a network service and that appears in the Network option in Control Panel can be removed by selecting it and clicking the Remove button.
You can use System Policy Editor to turn off services by setting system policies, or by using Registry mode to modify a computer's Registry. To do this, in the computer properties, click System. Then delete the services that you no longer want under the Run and Run Services policies.
Some agents, such as the SNMP agent, can be removed only by modifying the Registry. For a single computer, you can do this by using either Registry Editor or System Policy Editor. The following Registry keys list the services running on the computer:
Hkey_Local_Machine\Software\Microsoft\Windows\CurrentVersion\RunServices
Hkey_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run
