Settings app - Network & Internet - set connection to 'metered', and avoid the auto install of all new crap. I was fortunate to get this done before this update released, so I can avoid the nightmare I had with fall creators update. Too late for many, but a trick to keep in mind for the next 'feature' update which will happen, as night follows day.
I'll permit the April update after at least the 3rd bug fix... and after a stiff drink.
Windows nags me that there are updates that need to be allowed, I shun the message.
