Once I have a Windows VM that's stable, with the apps that I usually need, the rest of it takes little time. Mainly it's Excel that I need. And I need it to use all available CPU cores. I suppose that might work in Wine, but that seems like an iffy approach. Why do I take such precautions? Well, I've been an anonymous coward for a couple decades. I've corresponded with many people, and played with many projects. I honestly have no idea who might be after me, or for what. Ideally, nobody, for nothing. But ... Given that, I take whatever precautions I practically can. And it's also a hobby. Perhaps like building little ships in glass bottles. But hopefully maybe useful to someone.
