Bad news for owners of dedicated retro rigs: Steam is dropping support for Windows XP and Vista on January 1, 2019, Valve announced this week. And the deadline isn’t just for feature updates. If you’re still running one of those older operating system next year, Steam won’t work on your PC whatsoever.
Steam supported the legacy operating systems for far longer than most software, but Valve says the program’s underlying nature requires it to sunset Windows XP and Vista.
“The newest features in Steam rely on an embedded version of Google Chrome, which no longer functions on older versions of Windows,” the company wrote. “In addition, future versions of Steam will require Windows feature and security updates only present in Windows 7 and above.”
