We have modified an update package to run a custom command line.
If we deploy the update using a policy, the custom command run as expected
But… If we deploy the package with the new task named “Windows Software Update Installation” (from 8.5 RU2 if I remember correctly) the custom command is not run as expected. The task only run the altiris default command.
Even if we create the task using this document, only the default command is started.
