At uni we had "pleasure" to attend lectures held by some really old professor. First one was total disaster, since he had laptop that should be already taken to the museum. He tried to connect the projector, but I am almost sure that Windows 95 does not support it. Of course he called help, but the other guy was obviously no help. To our suprise professor canceled the lecture and next time he showed up whith brand new laptop with Windows 10. Of course there were troubles with the projector again 😂
