Difference in HAT screens

I noticed that the HAT screen in 2006 is different than 2004. Actually there are certain functionalities that are absent in 2006. i.e "Operations" and "Configuration".
see below:

Trying to figure out as if how to terminate the "instances" in 2006 . In 2004 it was done by going to "Operations" and terminating the instances. Do not see anything similair in 2006 as for now. I think I have the answer, it can be done from Biztalk Admin Console
