Linux is a viable option, but most people prefer Windows because it runs all of their favorite software, including the latest games. And for those who were still holding on, Windows 7 has officially reached its end of life, meaning it won't get any more support or security updates. Fortunately, you can get Windows 10 for free or cheap, if you know where to look.
