If you are a Windows XP or Vista OS kind of person that games, you will be out of luck when it comes to Steam on January 1, 2019. Official Steam support will stop on that date. As for now, the new Steam Chat will not be supported either. I still have an XP box running here with a 35w Athlon in it, but it is not used for gaming. The newest features in Steam rely on an embedded version of Google Chrome, which no longer functions on older versions of Windows. In addition, future versions of Steam will require Windows feature and security updates only present in Windows 7 and above.
