Just read the thread.
Global Updating is disabled, the default AutoUpdate task is disabled. I did however manually update the DATs this morning.
Will install VSE 8.5 patch 5 now and will let it update its DATs through the scheduled task. Let's hope patch 7 is not being applied then as well (patch 7 is checked-in in ePO).
Thanks Joe. You are correct. Good to know...
