Gee, you don't have to do much.
Installing one of the service releases (can't recall which one, but certainly 7.2(7)) disables the Windows SNMP service and installs the Cisco version of the SNMP service which it then starts.
Then you use the mmc snap-in to configure it as described in the "SNMP Guide for Cisco ICM/IPCC Enterprise" Release 7.0(0) July 2005. It's all there - what can't you follow?
