If you have been running your Steam account on Windows XP or Windows Vista operating systems, it is probably time for an upgrade. Steam has announced that it will official stop supporting the two Windows OS starting Jan 1, 2019.
It states on its website that users are encouraged to update to a more recent version of Windows in order to continue running Steam and any games or products purchased through the platform. The announcement was made as the newest features on the gaming platform rely on embedded version of Google Chrome, which doesn't function on older versions of Windows.
