Lot of “unnofficial” claims were touted to say Window’s 10 was supposed to be the last windows.
“windows as a service” model was definitely touted in the past with windows 10. No one believed it then, I don’t believe Win 11 is the final OS either.
These companies like using both strategies of service license model and a retail copy model to charge as both as a stand alone and a subscription.
