UPDATED 11/13/2024: The Windows 11 build 27749 ISO file is now available for download through the Microsoft support website to test the latest features and improvements using a clean installation or in-place upgrade.
The company has released the official ISO file of Windows 11 in the Canary Channel to allow developers and enthusiasts access to the next enhancements coming in future releases of the operating system. The ISO contains the latest preview, which means this is not meant to perform an installation on your primary computer.
If you are already a member of the Windows Insider Preview program, you do not need to download the ISO file for build 27749 since you can use the “Windows Update” settings to download the most recent flight.
