I‘ve had several faulty Windows updates in recent years and my machine is pre-built. And going by the threads I sifted through in search of solutions I am far from the only one. It‘s perfectly fine to not have the newest update at all times so as long as you update once a month when you can afford a potential faulty update. Having an older than most recent version is far from your biggest concern regarding security. I would even say it‘s a non-issue compared to good old fishing mails.
