Re: A serious question.
Each test image shows pictures of three anniversary wedding gifts: one for the first year's anniversary, one for the second, and one for the third. They're laid out like a glossy magazine advert. Each gift has a title, under which is a paragraph of descriptive text, and beneath that is a click-through link. In the low signifier version, the click-through link is not underlined and is the same colour and font size as the paragraph of text above it. In the high-signifier version, the links are a underlined and in a brighter blue. That's the scale of difference we're talking about. We're not talking about putting 3D buttons around the hyperlinks or the kind of design you're outlining.
You could pull apart the test in multiple ways. For example, the heat map shows the user looking at the title the most. So if the title had been hyperlinked, all would have been well. It was insisting users use a piddly hyperlink under the page was caused the problems.
But the design is more suspect than that. Because a shopper is not going to go, "You know what, I won't buy the second year's anniversary present this year, I'll buy the third." So it didn't need complicated exposition. It just needed to get the shopper to answer the question, "How many years have you been married?"
As for Windows, you'll have to ask the haters. I barely noticed the difference between Windows 7 and Windows 10. But I don't user Microsoft's dev tools or Office, so I'm not deeply exposed.
