We have a update deployment template set with the following settings:
Suppress display notifications on clients
Template Duration 2 weeks
Allow Restart outside of maintenance windows
The maintenance window is set to Saturday at 5:00PM to 9:00PM. For an unknown reason, the clients are still being given the ballon pop up and choice to "Install Now" or "Advanced Installation" during the software updates. We need these clients to just install the updates and reboot.
