Control different windows desktops using several keyboards and mice

Hello guys, I want to control one PC using 4 monitors and 4 keyboards and mice with windows. I have thought in purchase a reverse kvm switch to doing so, but I actually don’t know if it is going to be possible to divide the windows desktop and each keyboard / mice will control one of them. This solution is for a cyber coffee to reduce costs by buying several PC’s.

I will appreciate your help!!
