Why is everyone else being so dense about this question?
We want to display the margins, not the text boundary, not the ruler, which are both very easy to find. Removing this feature, or making it hard to find, would be a major blunder by MS. They couldn't say more loudly that they do not care about their product
or their customer.
Sorry, "everyone" on this forum is not being "dense" about the question. The "dense" entity is MS.
Repeating the answer that has already been provided, Word 2013 (and later) no longer offers the option to display "margins". As far as MS is concerned, the way text boundaries/margins were displayed in Word 2010 (and earlier) was "wrong". The official
position is that they "fixed the problem" (as they saw it) giving us the carpy display in 2013/2016. Sorry that is not the answer you (and everyone else) wants to hear.
MS does "care" about their products. But what is important to MS is maintaining income from the products, aka new sales, rather than the actual quality or usability of the product.
Yes, MS has consistently shown they don't care about their existing customer base. My guess is that they are assuming that like drug users we are so thoroughly "addicted" to their product that people will not switch to the alternative programs. The change
from menu's to the "ribbon" was entirely driven by desire to make the programs "easier" for "new" customers, and assumed that existing users would "adapt" to the "improvement". The same thing applies to the move from the Windows "desktop" to what
used to be called the "Metro" user interface with it's clunky tiles in Windows 8/10
