I think it's going to take a Microsoft catastrophe, something that disables machines for at least a few days. I'm thinking maybe a buggy windows update.
Or a forced update to windows 11 on machine that doesn't support it. That would break the windows install for good. Either they will find a way to install windows again or take it to somebody who installs windows on it again. Maybe maybe they'll find out about Linux.
You guys know that MS rolls out updates through a system of multi-layered opt-in channels and deploy to the wider channels in chunks over longer periods of time, right?
They may not be the most competent or scrupulous megacorp, but they do hire actual software engineers and stuff.
