What versions of Windows are supported?

What versions of Windows does Discourse support (I cant find this info anywhere…)

@Andro

Which are not listed in the supported browsers list given here on Meta Discourse.

What is important to highlight is that Discourse doesn’t support any Windows version that Microsoft themselves don’t support.

With that out of the way, I have tested myself that users from Windows XP upwards can get it working with minimal effort by installing a modern browser fork:

Dropping iOS 15 & other old browsers in July 2025

Fun exercise I just did: Windows XP IE 6 gives a TLS error [The image shows a Windows with Internet Explorer displaying an error message about a page cannot be displayed with the option to diagnose connection problems highlighted in red. (Captioned by AI)] Same Windows XP using a browser that still supports it (Supermium) [The image displays a blog post from the Discourse website on dropping iOS 15 and other older browsers in July 2025, announcing that new stable releases will be outdated …

Given that Windows XP is turning 25 years old, and much older than Discourse itself, it is impressive that this is even possible.

That means I have to search what browser versions all the versions of Windows back to 7 support.

Firefox support for Windows 7, 8 and 8.1 | Firefox Help

Looks like Firefox 115 ESR is a good bet.
