WHQL standards _should_ mean that for any PC purchase today (and many in the last decade or so) Windows Update will always have the most up-to-date "basic driver" on its servers.

There's some controversy (linked elsewhere in this thread) that those basic drivers are allowed by Microsoft to advertise their "full bloat" versions in notifications and launch time popups. The flipside to that controversy is that if you want the "full bloat" versions (such as the Geforce Experience if you are a game player), that makes it easy to acquire them as it is general a case of go through the notifications and popups on first launch, from what I've seen.

I don’t believe you would, drivers come in via windows update in modern windows. You should at worst miss cutting edge versions made available on the manufacturers website prior to arriving on windows update.

My Dell periodically scans for drivers and bios updates, and asks me to update them if a newer version is available.
