Again, why use Windows at that point?

At that point please just use another OS. You should be keeping your OS up to date.

I really don’t like the trend of things that should be articles, being videos instead. And I’m very unlikely to watch one of these videos. However, this is a personal preference and I don’t necessarily think videos should be banned from this community. Instead upvotes/downvotes could decide that; if no one wants to see videos, no one should upvote them.

For context, my threat model doesn’t need to account for real people breaking in and accessing my computer, the damage would be very contained.

I mean if you don’t have open ssh ports on your computer or whatever I don’t think you need a strong password, given that you’re not concerned about physical access. I would say that at the very least have a reasonably secure root password (/user password if you’re a sudoer/anyone else who can get root permissions with your user account) because if you end up with some malware on your computer that can, say, enter passwords, you don’t want it to be ridiculously easy to bruteforce.
