Why?
Turn off auto updates if you rather not. Lots of people do, and lots of people blame Microsoft when they miss a critical update and something goes wrong.
For years people derided “patch Tuesday” as some monthly obnoxious process, and surprise, now they consider it to be a beloved institution.
At work it's certainly better to have 'em batched. I think of it as "PMS Week" for all the Windows machines (oops, is that politically incorrect?). Git 'em all done and forget it for three weeks.
At home I don't care if patches get distributed through the month -- as long as I can make them NOT DISTURB ME while I'm doing stuff that's time critical or can't tolerate interruptions. Apple has been that way all along -- OS X updates become available, and they ASK POLITELY when would be a good time to install them.
Microsoft sometimes doesn't learn even where there's a perfectly obvious good example right in front of them of how to do it properly.
My objection is to "SURPRISE!! Sorry if you were working, your computer is tied up and then will reboot." Which is what this new deal sounds like so far for the home user.
