Hmm, I've seen that text before on some windows 7 computers at my school, it was about 2014-15. Anyways can you explain the 'trivial properties' included with the activated version?
Win 10 is different than 7 or 8.1
Previous version would run 100% unencumbered for 30 days.
Then, it would start an increasing level of annoyance, eventually shutting off completely every hour or two.
Win 10 starts the annoyance from Day 1, but it is trivial.
Can't customize the desktop background
Can't customize the Taskbar.
And the above mentioned nag text overlay that appears whenever it feels like.
And of course, MS could simply cut off unactivated versions whenever they see fit. There is no guarantee it will continue to work forever.
Having said that, I have a Win 10 Pro running in a VM to test this specific thing. Installed Dec 8 2016, so almost 11 months old. Still running just fine.
My real systems are, however, all valid activated versions.
