Do keep in mind that none of these links are official.
Given below are the various download links for Windows 11 ISO files. So please refer to this guide: Download and Install Windows 11 Insider Preview Build. So it’s better to try out the official Insider preview build and not these leaks. UPDATE: The First Official Windows 11 Insider Build is Now Available. From this post, you could now download the Windows 11 ISO file and Virtual Machine file having the build number _release_CLIENT_CONSUMER_圆4FRE_en-us.iso. Well, it’s time to put this issue to rest. However, the only issue users are having is the unavailability of the ISO file that you need to supply to the Virtual Machine or for mounting purposes. Along the same lines, you may also mount the Windows 11 ISO in the USB Flash Drive using the Rufus tool. But if you are among the tech enthusiasts, then you could install Windows 11 on a Virtual Machine such as VMWare right away. However, even though the OS is now official, it is yet to be made available for download from the Microsoft Site. Right from the UI changes to the taskbar now occupying the central position, the changes are there for everyone to see.
