Is that an update, or an OS Upgrade ?

I haven't seen that dialog, because I "force install" all
my OS Upgrades as soon as they're available.

Your dialog almost looks like a transition from 15063 to 16299.

Running "winver" on the before and after, would tell you.

Using the "revert" function within 10 days of an Upgrade,
would allow you to go back to the previous release.

Long sordid story. It's probably "somewhat" related, but almost certainly
not completely related.

It's not related because Opera has been working for about a year (or so),
and only recently (days) started hanging.

It's perhaps related because my Win 10 Pro has *everything* possible turned
off. That means all cortana, all suggestions, all tracking, all updates,
etc.

So *every* Windows-forced update fails in the end, even those I let go
through fruition.
Start Run cmd winver
Version 1511 (OS Build 10586.1106)

Note: Microsoft *says* you can't stave off an update forever - but you
certainly can - as mine has *never* updated and it's a perfectly valid
release (I just turned off one too many things - and I don't know what it
was that finally killed *all* Windows updates - but they're dead).

I'm not worried about the Windows update, nor really about Opera hanging.

What I'd like to know is how to debug *any* process that hangs.
We've got a good start with this Nirsoft tool - but - what next?
