Microsoft released the Windows 10 version 21H1 build 20150 from the development branch, code-named "Iron". This is the first preview build for the next major feature update to release in the first half of 2021.
Now the company has also released the ISOs for the Windows 10 21H1 build 20150, so if you want to do a clean installation, you can do that.
Just a day ago, Microsoft shared the plan to use a new channel model for the Windows Insiders to deliver preview builds and released the first build in the beta channel for Windows 10 version 20H2.
Within a day after the announcement, and the release of the first 20H2 beta build, Microsoft now released the first developer preview build for Windows 10 21H1 from the Iron development branch.
The company also announces the ISO image for Windows 10 version 21H1, so if you want to perform a clean installation, you can do that immediately. In general, Microsoft doesn't publish ISO images this early in a development cycle.
If you want to download the new ISO images for Windows 10 (Version 21H1) build 20150, login to the Windows 10 Insider Preview Downloads page. Verify which edition of Windows 10 you need to download, select the product language, and download the bit that you want to install.
As usual, you can get the ISO for Windows 10 Insider Preview, Windows 10 Insider Preview Enterprise, and Windows 10 Insider Preview Home China.
