Windows' might be complex, but it is NOT graceful. If you have notepad open with unsaved text, then shutdown will never shut down - but nothing on the screen will make this obvious to a non-technical person.
This isn't the default behavior of Win10 Pro without a DC. I don't know enough about graceful shutdowns to have a perspective. Maybe Home has a different user presentation than Pro?
Unrelated: I'm trying to get from two Virtualbox Mint VMs to one paravirtualized (docker?) image, then to move to physical hardware. When I'm ready, where in the fediverse should I ask for assistance?
