Microsoft has been testing the upcoming release of Windows 10 for months now. Windows Insiders have been testing Windows 10 20H1 (aka version 2004) over the past several months, and it’s slowly getting closer to a public release.
As you may know, Microsoft released the RTM (release-to-manufacturing) build (19041) for Windows 10 20H1 to Insiders back in December, and it’s releasing the official ISOs for the build to Insiders this week.
Microsoft does not have an official announcement for this, but only a tweet that confirms the release of build 19041.84’s ISOs, which you can download from the Windows Insider site here.

The release of the ISOs means you can now perform a clean install of your machine with Windows 10 20H1, as it’s fairly stable nowadays. Still, I have been using it for the past week or so now, and there are definitely a lot of rough edges and bugs as you would expect. Microsoft is, however, yet to announce an official release date for Windows 10 20H1, and all of these bugs will probably get addressed before the public release.
