    Well it has been years since I used ObRegisterCallbacks but you do not specify the process you are monitoring, it basically calls for all CREATES or DUPLICATES of handles of type either process or thread. So you don't set the call on a specific process, you create a callback that has to determine if this is a process you are concerned about.
