Yes, you can. You can find the CLI guide here.
Change control events roll up into ePO by default. You would not see the events in event viewer.
QQ: What would be the reason to change policies from the client?
Can you give me example of adding a path via command line.
Is the modification through CLI also possible for application control???
AA:This is because if epo server goes down and in any case we are not able to restore it.So,we can use command line if some urgent requirement is there
