Those stupid MFD machines have been the bane of my existence as a sysadmin ever since I started in this career many, many years ago.

It's these machines, plus a few really old windows-only apps deep in basement of enterprises that keep this old tech around. There's usually no budget to remedy, and no appetite to either from leadership

Its also what happens when the people buying the tech are disconnected from the ones implementing. Microsoft caters to this.
