"Microsoft later clarified that Windows 10 would be updated continuously as a service."
This is the problem. It wasn't.
Microsoft then made Windows 11 with arbitrary requirements that many older computers can't meet. While there are ways that users like myself can get around the requirements, we shouldn't have to, because we were promised that Windows 10 would be the last version of Windows. Is Microsoft really going to put millions of computers at risk by cutting off updates (except for a small percent of customers willing to pay for the service) only to turn around and release Windows 12 and announce the end-of-life date for Windows 11, screwing over all the customers that managed to upgrade to 11? I am certain that Microsoft is looking to turn Windows into a paid subscription like Adobe did to its customers, but forcing people into it like Adobe did will only give people the incentive to look for alternatives like millions of people are doing with Adobe software. If they offer it, it should be an option that people can choose. They could make it bundled with Office, OneDrive, and maybe Skype or other options to sweeten the pot. I doubt they will. But that would be the right way to do it.
I know you don't know the answer. Probably neither does Microsoft. But we can all see where this is going.
