In my experience, don't. Offer them your best solution for a novice user, which for me is usually an up-to-date machine with an ad blocker, and make sure that you're open for

Ultimately, they're adults, and the last thing your father will want is to be treated like a child on his own machine. If he fucks something up, fix it, and tell him what he can do to not have that issue come up again.

This is good advice in principle but my parents are from a different world they grew up in a world without fridges, TVs or electronics.

I am all for them learning and making their own mistakes but I know them well enough to know that this wouldn't really work in their case - I know them well enough that ultimately they want something that just works with minimal effort, the stakes are also high in that I don't want them bricking a PC (100s of $) or getting hit by identity fraud.

I'd go mac if my dad didn't hate it so much.
