W10 keeps updating even tho updates are turned off

Critical updates could ignore metered connection without a second thought.
M$ once ignored my metered connection, prompting me to use scripts to control Windows Update.

I take it to mean "No automatic updates, period!"

And no updates that belong to the specific 'category' that WUMT/WuMgr can't find.

I have never had that happen to me, prompting me to never use any 3rd party mechanisms or scripts to control Windows Update.

Or, whatever happened to the old "don't fix it if it ain't broke".

M$ does not ignore your metered connection because you are lucky. Hopefully, you never have to fix it.
WUMT/WuMgr can't find optional updates at my end.

Time = money so I prefer to spend my time fixing that which actually does represent ROI (Return On Investment). Only sometimes, I like to have some fun playing with Windows 10 intestines... but I can think of many more interesting creative hobbies than creating problems where there are none.

Let's spend some time helping the OP fix the problem rather than talking about creative hobbies.

Incorrect. You are assuming I don't have antivirus and a firewall (and other protection too, actually)?

There are certain types of vulnerabilities that no antivirus or firewall can fix. Although adding extra layers of protection can be a good thing, allowing Windows updates is exactly that: adding an extra layer of protection. Every layer comes with its own unique set of both pros and cons.

I have a formal degree in IT and I have received extensive professional training in Java Enterprise software development (EJB)─which is what every large corporation typically uses only because there are experts who thoroughly understand the simple fact that everything has both pros and cons. My point being, I am used to those types of environments where the pros outweighing the cons is top of the list of critical success factors. In a typical SOHO type of scenario, for 'hobbiests', running in a VM isn't necessarily always the best among possible solutions. It would only slow me down. I don't expect many people to understand why. The harder I try to explain, the more confused everyone always tends to become. For the most part, I have stopped bothering to explain the key strategic fundamentals to those who never listen anyway in the first place. I have said it before, and I will keep saying it. I don't do bottomless pits. Period.

Mine is a normally accepted emphatic form.

My definition of being empathic is different from yours. As for what's normally accepted, that simply depends on what kind of environment you are in, as different groups of people have different convictions, and, the gifted do not very often belong to the largest groups of people, which is an observation that is still easily overlooked by many─not only in the IT branch of society.

It doesn’t follow that you are superior to the top member here.

...Which immediately helps to explain why I never claimed to be superior. I.e., your wrong assumption that I think I am superior says more about you than it says about what's the most sensible.

I am not interested in making assumptions about what you think.
