WaaS is very difficult to manage. The updates / feature upgrades and deferrals are all just wishful thinking. When Upgrades are shoved down our throats they don't even obey the Active Hours schedule and restart a system during production hours without prompting. It's amazing how your AI deems a new buggy release is stable for business within only 45 days of testing for an enterprise environment; but in the world of Green Screens, Blue Screens and just outright unusable, unstable Windows 10 systems, we all know that this is far from the truth. Download and Pray. Quality Control seems to really be an issue. In regards to communication, there really needs to be better notification when a device is going to be auto downloading the latest feature release ultimately causing downtime.
