msf > use post/windows/manage/delete_user
msf post(delete_user) > show options
    ... show and set options ...
msf post(delete_user) > set SESSION session-id
msf post(delete_user) > exploit

If you wish to run the post against all sessions from framework, here is how:

1 - Create the following resource script:


framework.sessions.each_pair do |sid, session|
  run_single("use post/windows/manage/delete_user")
  run_single("set SESSION #{sid}")
  run_single("run")
end

2 - At the msf prompt, execute the above resource script:

msf > resource path-to-resource-script
