Why are you expecting obscure Windows advice (MS obscures it because they want to continue nagging people to use their shit) from people who gave up entirely on Windows?

MS is nagging people to use products they don't want to and now you're nagging someone who doesn't use Windows for advice that they likely don't know and probably don't really care to find out.

There's probably a way to prevent this specific pop-up from appearing, but that solution may or may not apply to future pop-ups. The only way to guarantee windows will never nag you is to not use it. Even giving in will just prevent this particular nag.
