I went through this update process (from 1803) to Win 10-"1903", it took like an hour with multiple restarts, when it was over, I had to restart my PC and log back in.

Upon logging back in, I was sent to a "Temporary platform" without access to any of my usual Desktop activities; anything that I created would not be saved when I logged out was the prompt that I received. I was prompted to log back in to fix the problem so, I logged back in to my LIVE, account at outlook and *my* computer came home to me.

My Win 10 computer is nothing more that a dumb-terminal / Client with storage; without the permission of Microsoft, I cannot use my computer or the Windows software that I purchased.

I downplayed the fact that the same desktop shows up on both of my Win-10 computers; what happened to local machines?

All these active connections running in the background! WTF?

BTW, I don't see anything running on Port 80.
