Microsoft Randomly Force-Feeds Ads to Windows Users

Using Microsoft software sometimes is its own punishment. Worse, the punishment occurs randomly. We may have been working along happily enough, but suddenly the software shows a picture (with a promotional comment about one of its products, e.g. its Edge browser) and demands a password. Oh, we think, this is the new way. This way continues for a while, but then it flips back to the previous no-password/no-ad.
