Arguably, but I'm not sure. Usually, enshittification is when something starts out really good, but then the management tries to squeeze more "value" out of it by making it worse and worse in ways that make the company more profit, but makes the experience worse for the users. In the case of Windows, personally I don't remember it ever being "really good" in the first place; it's always been shitty, just in different ways. In the past, it wasn't shitty in this particular way, but it was shitty in other ways. They fixed some of the really shitty stuff (blue-screens all the time, bad vendor-provided drivers, etc.), but every time they fixed one shitty thing they added a new shitty thing.
