I would love to see where it would go forward from there, but our puny human minds surely could not handle the Eldritch strangeness that would entail... (or rather, we could only do it once, then go insane forever afterwards - sign me up!:-P)
I thought some of the older ones, like 2000, were more secure, with ability to access on-chip security features. So ofc they threw all that out in favor of 10, the final OS that would come as a subscription service, meaning that you'd never need to buy one again. And then they threw that out too, in favor of the next one... and on and on it goes:-P.
Computers mostly don't force software updates on you, unless you tell them to. (Caveat: IT routinely forces updates on people.) Find the setting where you specifically asked the machine to keep itself updated, and turn it off. If you can't find it, throw the machine away and get a better one where you can be in control:-P. This concludes my sermon for today, I hope you all have some Happy Holidays!:-P
