Yeah, I was really confused by this, since I very clearly recall seeing ads on fresh Windows computers, along with guides etc on how to disable them.
I know back when I used Windows I had an entire routine to disable all the annoying stuff, so I suspect they disabled all the annoying stuff and totally forgot.
I really don't get the need to "defend" Windows, however. It's an OS being sold by a large, for-profit company, that has pros and cons like any other OS. No need to fight MS's fights for them... and given it's 75% desktop marketshare (and like ~95% for gaming), I think they are doing pretty dang well by themselves.
