For what its worth adblockers are likely hurting windows 10's numbers. Many users are keeping their old systems active whether it be the windows 7 or something older. If the prior machine was rather high end when it was bought theres no real reason to retire it until it breaks if its performing functions that newer operating systems cannot without significant retraining or learning. A kvm last year was my mothers favorite gift for christmas. She can play her old puzzle games, printer and scanner continue to be usable and work flawlessly and she can send and receive faxs from work and the best part is I don't need to waste time getting her stuff to work.
