It's been a long time since I used dos/windows, but is it really "C:/>" at the prompt nowadays? Used to be "C:\>" back in my day
I had a relative contact me a couple of years ago to ask if the little black box her grandson had helpfully connected to the TV was "dodgy".
It starts off as a prompt and becomes an html tag. It's like how my father-in-law begins a joke that ends as a riddle.
