Where would the ranking be better? In universal articles or narrowly focused ones?

Question

Sphinx

Let me explain the issue with an example.
For example, I have an article on how to install Windows. I can write about the installation of each version ( win95, xp, 7, 8, 10 ) with easy navigation from the content, BUT then users of a certain OS ( for example, win 7 ) will simply scroll through all other content not related to their OS version, which is essentially I think bad. On the other hand, it will be convenient, because everything is in one place. In the top for different queries - different articles. Somewhere everything is collected in one, and somewhere in pieces. And I wondered...
Is it worth writing everything separately or is it still better for ranking to cram everything into 1 article?
Experienced people, tell me please!

Answer 1

1 article - always 1 response to a search query.
(if I only need win8, I don't want to waste energy on parsing the dump)

Answer 2

Of course, you should not shove instructions for installing Windows 3.1 and Windows 10 into one article.
But if these are similar systems, for example, Windows 8.1 and Windows 10, then why not.

Answer 3

Make it “universal”, with a normal table of contents, fragments should be available by hash, and try to index them in search engines (Webmaster), and you can also attach “narrowly targeted” “mirrors” to the “universal” (pages with separate meta tags , but, with body from "universal"), let's wipe Google!

Answer 4

Depending on which one is better to write ....
