Microsoft has released the official ISO images for Windows 10 version 21H2 for them Insiders (build 19044.1202). The same version is currently also available in the Release Preview channel. So now you can download the ISO you are interested in and do a clean install of the latest version of Windows 10.
Release Preview builds are pretty stable. Despite being a pre-release version, it has changes compared to the current “stable” version. As with the 20H2 and 21H1 versions, the new 21H2 version will be a small cumulative information for Windows 10 version 2004 with some minor changes. All the above-mentioned versions of Windows 10 share the same base code.
Thus, Windows 10 of version 21H2 is based on the same code as versions 2004, 20H2 and 21H1. In addition, all changes from 20H2, 21H1 and 21H2 were added to the 2004 version with cumulative updates. They are simply hidden and must be activated with an "activation" package. So it is very likely that the upgrade to version 21H2 at this time will not affect the user experience.
