I have the following scenario:
- Install Windows with MDT
- MDT installs the ZENworks agent
- MDT would run zac bin "core_bundle" afterwards. The core_bundle would install all the software I require for my machines

The problem I'm facing is that while the core_bundle install, all the assigned bundles (say, bundles assigned with the "install on refresh") will also start to run generating conflicts.

- I have a bundle that install a MSI file
- I want that to be installed on all the machines at OS install time, but also to existing machines. So I schedule it to be installed to all machines on refresh.
- My core_bundle will start installing the MSI file, but because the "run on refresh" assigned also starts, the first installation fails

So, the question is how to disable all scheduled bundles while on MDT?
