Disable SNMP (Windows Rackmount)

You can disable SNMP through the Windows Services console. From the command line, Run the following:

services.msc

Then locate the following items:

SNMPService
SNMPTrap Service

Open the properties of each service, stop them, and set their 'startup type' to "Disabled."

You can do this from the command line as well (requires a command-line window with elevated administrator privileges)

First stop the services:
net stop snmp service
net stop snmp trap service

Then disable the services:
sc config snmp service start=disable
sc config snmp trap service start=disable
