Bruce can't get the latest Windows Update 1903 on his HP laptop. Microsoft says that this BIOS is too out of date and as such, it'll fail and roll back. Is there a way to block it so it won't keep doing it? The problem is, that Microsoft has stopped supporting 1803, which is where Bruce is stuck, and as such, he won't get security updates starting at the end of the year. That's a real concern. He tried putting it on a metered connection and that does stop it, but he's worried about security. He still wants the security updates. Leo says that he can force them, but it will then try to push the feature update. Leo isn't so sure that firmware being out of date is the issue. But he could search the motherboard for an updated BIOS.

The only other option is to buy a new computer. Or he can put Linux on the old one.
