Steam Games Will Stop Running on Windows XP & Vista Starting Tomorrow. Avast Will Also Stop Supporting Its Products for the Two OSes.
Earlier this year, Valve announced that it will be dropping support for Windows XP and Vista starting January 1,2019. Those who continue to be on XP or Vista will have to upgrade to Windows 7 or later if they wish to use Steam.
The decision was made after the continued decline of Steam gamers on these platforms, with less than 1% of its userbase coming from these two operating systems.
