The answer is "maybe":

0-updating-will-work-devils-in-details.html

Part of which surmises:

" •When the patch looks good, it'll go to Windows Insiders in the Fast
ring. (There may be a "Ludicrous ring" at some point, but there's been
no official word from Microsoft.)
•Once the Fast folks have hammered on it for a suitable amount of
time, the patch will go to the Windows Insiders Slow ring.
•Having passed Slow ring muster, the patch heads out in two directions.
•First, the Slow-approved patch goes out to all consumer Windows 10
customers -- the ones with "free" Windows. Consumers have no choice
about it; they will get the patch, thereby being updated to the "Current
branch." Presumably Windows 10 will have some mechanism for prohibiting
reboots at specific times of the day, but that's the extent of
individual customers' control. There will be no ability to shut off
automatic updates (short of permanently disconnecting from the
Internet), no provision for blocking specific updates, and no way to
roll back updates -- either one at a time, or en masse -- should they
cause problems. I haven't seen any official announcement that lays the
process out quite so starkly, but that seems to be where we're headed. "


The full article makes the update situation as currently being tested
sound much better than it is.

I'm bogged down in a Synaptics update situation at the moment where an
update cured a problem (not the major one that seems to have affected
others), then a new build came out which took the situation back to
where it was before, then yesterday there was another update. I haven't
had time to test yet.

Update history doesn't seem to have a scroll bar, so you get a page of
Defender updates and no clue as to whether you have the real updates
installed or not, no easy way of checking what they were and no easy way
of opting out.

And what do I do when W10 is 2 years old and I have the original
recovery disk or partition and my ssd wears out and needs a new one. I
recover from the media I have and then need 2 years of updates. My
experience is that these updates need to be done in the correct order or
in small batches to avoid recurrent update failures. An automatic system
will make this impossible.

I think I understand what Microsoft is trying to do - to get a mass user
base on the same universal up to date OS. The trouble is that as I see
things now Windows Update has become the game killer.

Also, what happens when the Windows Insiders get bored and gradually
drop out. Who will be testing for the great corporations then?

Still, to make this work, they will have to provide Insiders with a
current free OS on a permanent basis. I might sign up to that.
