In 2020, when Chromium-based (open source) Edge was released, the Microsoft surprised everyone by offering support for older and outdated operating systems such as Windows 7, 8 and 8.1.
This movement of Microsoft appears to be coming to an end as the company prepares to stop supporting Edge on versions of Windows released before 2015. The latest version of Microsoft Edge Dev is now only available for users of Windows 10 and 11.
It is worth noting that the stable versions of Microsoft Edge, the Chrome and other Chromium-based browsers still support Windows 7, 8, and 8.1 (Chrome asks its users to update to Windows 10 or 11).
Developers will stop offering updates for older versions of Windows early next year after Microsoft ends its Extended Security Updates program for Windows 7.
As for Firefox, the Mozilla should decide when to stop updating Firefox on pre-Windows 10 systems.
