Windows Insiders can now download ISO files for Windows 10 19H2 build 18363, and Windows 10 20H1 build 18970 (via Neowin). These ISO files allow you to perform a clean installation of their respective build of Windows 10. Build 18363 is the first build from the Windows 10 19H2 update to have an ISO released. Build 18970 is from the fast ring. You can get both builds at the Windows Insider site.
