Microsoft's dominating operating system is supported until 2025. A sizeable number of devices will be upgraded to Windows 10 once support runs out. Firefox users who run the browser on Windows 7 or 8.1 devices have a number of options: What appears to be clear is that Mozilla's support for Windows 7 and 8.1 will end in 2023. Firefox users on Windows 7 and 8.1 would be moved to Firefox 102 ESR, the current Extended Support Release branch, and would receive updates until Firefox 102 ESR is moved to Firefox 114 ESR this happens in August 2023. The second option that Mozilla considers extends support until the release of the next Firefox ESR version. Firefox on all Linux distributions, on Mac, and all other versions of Windows, including Windows 8.1, also have a user base of about 15%. The percentage dropped significantly in the past couple of years, but is still almost as much as the percentage of all other operating systems that Firefox runs on, with the exception of the dominating Windows 10 platform. About 15% of Firefox users use the browser on Windows 7 and 8.1 machines.

Google did not reveal how large the browser's user base is on these two Windows operating systems. The company told Chrome users who run the browser on devices powered by these operating systems that they could continue running Chrome 109, the last version to be released for Windows 7 and 8.1, but that the browser would not receive any more updates.

Google announced that it will end support for Google Chrome on Windows 7 and Windows 8 in February 2023. With Windows 7 and 8.1 ending official support by Microsoft in January 2023, software companies face a tough decision: should they support the operating systems for longer, or drop support at the official end of support date.
