Last week Microsoft released Windows 11 Build 22454 to the insiders in the Dev Channel. The build was released from the active development branch (RS_PRERELEASE) that adds a modern context menu to the Recycle Bin, network sharing in File Explorer, an updated version of the Korean IME, and a list of bug fixes.
Later in the week, Microsoft also released the ISO image of the same Windows 11 Build 22454. Being the first ISO image of the Windows 11 vNext release build, insiders can now perform a clean installation on their system.
How to download the official Windows 11 Build 22454 ISO image
The new Windows 11 Dev Channel Build 22454 ISO image can be downloaded from the Microsoft Official site for Windows Insiders. You need to be a Windows Insider to get the ISO image. Once logged in, select the edition and the Windows 11 build that you want to download. Next, select the product language to generate the Windows 11 64-bit ISO image link.
Do note that the generated link is valid for 24 hours from the time of creation.
If you are having an unsupported device, refrain from installing Windows 11 build on that system as Microsoft may refrain from providing any updates in the future.
Once you have downloaded the latest Windows 11 ISO image, burn it to a DVD or a USB device. You can use Rufus, or BalenaEtcher to create the bootable USB drive.
