Which laptops and windows on the ISS?

Which laptops are currently used on the International Space Station? Until 2016 only Thinkpads were approved. Which models are currently used besides thinkpads? Which Windows is used there. Are you already at 10 or 7? Linux / Unix is said not to be used so that the astronauts do not have to change from everyday life.
