I think they know that they have a shitty product that nobody asked and everybody hates, but they also know that corporations and institutions have their workflows and custom software stacks built on top of windows and therefore them and their workers are not very easily going to jump ship.

If it backfires, then it backfires, but even then Microsoft makes more money on Office 365 alone than they do from Windows.
