There are Windows computers in there. They are not connected to any outside network &quot;to be safe&quot;. Therefore they are protected, even protected from updates. Software that runs on them is validated for that specific OS version with a specific state of updates applied.<p>Regulations say you can&#x27;t just ran any random device (including software) there, that&#x27;s unsafe.<p>Unfortunately regulations weren&#x27;t being made with PCs in mind where anybody can plug in an infected USB stick. Or needs to in case he&#x27;s a service technician. (Yes, those ports are not available for &quot;anybody&quot; who is there, but somebody needs to install software on those machines).<p>There are things I have seen I wish I could unsee to feel safe.
