After Windows 1709 update on my Notebook, 2017.10 went into Demo mode. Ok, no problem, started CCC.
I have not started Sonar immediately, but when I started "Congrats. Sonar is no longer running in demo mode. Enjoy".
Rapture pro is also happy.
But guess what? CA-2A went into demo mode!

This is the kind of thing that makes you wish somebody was home at the Cakewalk store.

Fortunately no need for that. It has re-authorized automatically.
 
So my post is just the information for other:
a) it was known that AD2 has to go on-line after any major Windows update, but with Sonar that was not happening with me before (while I should admit I was always starting it after any update with Internet connection enabled)
b) it is worse to independently check other CW components after update

b) it is worse to independently check other CW components after update

I *think* (based on seeing it in another post of yours, and knowing that English is not your first language) you are confusing 'worse' with 'worth' in this sentence. Thus, it is *worth* checking other CW components after an OS update, meaning a good thing, rather than worse, which would mean, well, not a good thing.

Is this really still valid advice at this point? It kind of feels like you might as well be saying, write your question on a piece of paper, seal it inside an old bottle, and send it off across the waves, you're sure to get a reply sooner or later!

You are absolutely right, my spell checker is happy with both (why they are not "smart"?) and I have forgotten the difference (if I ever really knew it). Thanks!
