so i have one computer that is connected to another computer without a harddrive through a cat5 cable. i was wondering if i could run windows on the computer without a harddrive from the other computer through a cat5 cable.

You would have to hire me as a consultant for me to walk you through how to do that. I suggest you do some googling, reading, and research and see what you come up with. That sort of stuff can get complicated pretty quick.
Plus you would have to be running a server OS, which I doubt you own a license for.
