Mmmm - concerned that it installed without a prompt. With Server 2008 Patch Tuesday was all there was and everything ran smoothly - now they can throw more updates the week after and we need to hold them over until the following month and install everything on the Saturday after Patch Tuesday. If it's going to override our settings and start installing downloads that could be a problem.
Since Server 2016 we have disabled UpdateOrchestrator Reboot (and renamed a blank directory as the file to stop MS recreating it), but it still makes me nervous when I see 'We'll restart your device outside of active hours!'
Also - looking at that indicates it will only install .NET updates this time around?
