Microsoft Adds First ISO For Version 21H1 In Windows 10 Insider


Microsoft has now released a first ISO package for the upcoming Windows 10 feature update for spring 2021. These ISOs for the development branch 21H1 are available after logging in with a Microsoft account and enable a clean install.

Since the work on the new Windows 10 April or May 2021 update, alias Version 21H1, is almost complete, Microsoft is now increasingly devoting itself to the next feature update for autumn, Version 21H2. Until then, Windows Insiders and anyone who would like to try out a pre-release version won’t have to wait any longer. Because Microsoft has now published the first ISO files for the 21H1 development branch.

ISO with build number 19043

If Microsoft adheres to the previous release plans, the first feature update of this year for Windows 10 could appear shortly. The second, and as it is already called, much more extensive update, should come out in the fall. The release of a 21H1 ISO with the build number 19043 starts at least once. This is also the build that recently started beta testing. For the voluntary testers in the Insider Program, there is now the option of relaunching the new version.

You can get the new ISOs on a special download page, but you have to be registered in the Windows Insider Program and logged in with your Microsoft account.

Download for Windows Insiders only

The ISOs are offered as personalized download links for registered Windows Insiders. This website for downloads can only be used as a registered Windows Insider, the links generated are valid for 24 hours. You can register for the Windows Insider Program at any time with a Microsoft account and a supported device. The regular Home Previews, as well as the Windows 10 Business Version and the Windows 10 Home China Edition are now available.

The ISOs are available in different language packages.
