Steam has now officially stopped supporting Windows 7, Windows 8, and Windows 8.1.

Steam has now officially stopped supporting Windows 7, Windows 8, and Windows 8.1.::95.57 percent of surveyed Steam users are already on Windows 10 and 11, with nearly 2 percent of the remainder on Linux and 1.5 percent on Mac — so we may be talking about fewer than 1 percent of users on these older Windows builds. Older versions of MacOS will also lose support on February 15th, just a month and a half from now. Correction: It's macOS 10.13 and 10.14 that are losing support. Not macOS period.
