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.
It was during this time the transition to 64 bit systems became necessary to deal with needing to have more than 4GB of memory which was not helped by Vista using 2GB just to run, iirc. If you ran Vista 32 bit you had memory problems. If you ran Vista 64 bit you had major compatibility problems. It wasn’t until the end of Vista’s life did 64 bit go mainstream.
