Okay you tekkies: I just updated my PC from Windows 8 to Windows 8.1, and now I'm getting all these annoying pop up ads and promo videos I don't want. I turned on the pop-up blocker, but it's not helping. Sort of going back to Windows 8, is there some secret way to keep those unwanted pop-ups from, well, popping up? If someone's got an easy, step-by-step procedure, I'd be grateful. Thanks.
