In an exceptionally long corridor in a Space Station, there are one thousand windows along one wall. Coincidentally, there are exactly one thousand people in the station. The Captain orders the first person to open the blinds on every window. Then, he orders the second person to close the blinds on every second window. Then the third person is told to go to every third window, and close the blinds if they are open, and open the blinds if they are closed. The fourth person does this for every fourth window, and so on.
So, after all 1000 people complete the process, how many blinds are open?

I've done a riddle like this before and I understood it, but your version makes no sense to me whatsoever.
