Re: If you read the Windows EULA carefully, you'll note the words...
How about those annoying Blue, Green and Black rectangular popup boxes that call your attention to some clever new (and usually useless) feature of Office or Windows? I get 'em on my corporate machine. I think they're called "feature tips" or some such and there does not seem to be a way of turnng them off, except one at a time by registry entries. They're present in 10 and 11.
You have to explicitly dismiss them by clicking "got it" every time, and they pop up randomly. I call anything that is not directly facilitating the task I'm doing, advertising.
