“Don’t turn off” is the worst kind of status message.
When it eventually hangs for various reasons, you actually do need to turn off your pc for it to complete or to let it roll back in an error state.
When “just hang in there” is still present on the third day you’ll start wondering why you bought that piece of furniture and won’t mind the consequences of turning it off.
Console output with status of the current operation, including error and warning messages
The average user does not want to see that and does not need to see that. That’s how you end up with thousands of support requests of “why is my computer showing these errors?”
Things should be abstracted from the users by default. There’s no need for grandma to see a console output every time windows needs to update.
Not to defend Windows too much in a Linux community, but you can turn on verbose status messages for the screens you see during startup, shutdown, login and log off. It’s a setting that can either be turned on with the local or domain group policy, or by registry key.
Still though, it’s not as detailed as full console output, but is definitely more helpful than just telling you to wait.
