I'm trying to deliver bundles to workstations before the user login the first time on a newly imaged workstation.

We have a workstation group that all workstations become a member of when the ZEN agent is installed, and I have the bundles associated to the group but what is the correct event to get the bundle to install before the first login on the computer and what should I consider when creating the bundles so that they can be installed in that manner?

Best regards
