I work with a lot of people who use big CNC machines that run Windows.
It's no fun if you set it going on a two day job cutting a $2000 piece of aluminum and the machine decides to reboot at 2am because an unused component of Windows .Net got an update or Microsoft just had to install a new "feature".
nb. This even happens in LTSB versions of Windows that aren't supposed to do that.
(PS: Any adenoidal replies along the lines of "wouldn't happen if they use Linux!" will be mocked - the CNC machine makers make CNC machines with Windows software and the end users don't get much choice)
