You&#x27;re right. My bet is that they use windows because they want to save or get something from the machine (either to a USB drive or network)<p>And I would have followed the same steps you mentioned. The machine could work with Windows.<p>Windows CE might have been a better pick, so you can have things like RO filesystem, etc<p>&quot;There is no reason to use Windows&quot; is, as you mentioned, not a bad decision in itself, but since they do it the lazy way, it is awful. Not sure if there&#x27;s an out-of-the-box way of firewalling everything in the Windows versions available at the time that machine was built
