In the atmospheric/climatology lab there are a number of computers running very specific versions of Windows (down to specific patches) tailored to really obscure science research software packages, some industry standard, most custom-rolled and tailored to that project. Which means they're very fragile and need to be left alone.
Of course Microsoft blasts Win10 installer files down our very expensive, very slow satellite link, and proceeds to force Win7/8 systems to Win10 which broke a few multi-million dollar experiments in a place that takes MONTHS to get to in the winter. So effectively killed the research.
And yeah, you can argue "well you should've disabled Windows updates etc etc" but in REALITY, not perfect-theory world, you should be able to trust your OS manufacturer not to force-install a major OS revision without your consent. And in the old days of Microsoft, you could. Now they just say "f--- you, we're installing it regardless what you want."
That company can die in a fire for all I care.
