Steam will officially stop supporting Windows 7 and Windows 8 (and Windows 8.1) starting January 1, 2024. According to Valve, the newest features in Steam need an embedded version of Google Chrome, which no longer works with these older versions of Windows. Plus, future versions of Steam will need Windows features and security updates available in Windows 10 and above. So, if you haven't made the shift to the newer Windows operating system yet and use Steam, now is the time to switch.
