That doesn't make sense though. It seems to me that we should be able to uncheck Windows Update without also unchecking Recommended.
For example, "Recommended" protects stuff like Photo Codec, Image Color Management, Font Cache Service, and UI Ribbon. None of those have anything to do with Windows Update. We should be able to continue protecting services like those while unlocking Windows Update.
In other words, shouldn't Servicing Stack and Windows Update be a subset of Recommended and not the other way around as it shows now?
