Nowadays Windows is filled with adware and is fairly slow, but it wasn’t always like this. Was there a particular time where a change occurred?
When did they start bundling candy crush? Xp? Or 7? That was when the enshittification started.
Not due to that app itself, and it was a slow start and it took a while, but that was when stuff started being “pushed” instead of merely “present”, like, say pinball or solitaire.
