How to Download Windows 11 ISO 64-bit to install – Unofficial Way

Microsoft Windows 11 is there for Insiders who are using Windows 10, as an upgrade, however, if you want a clean installation on your PC, then still that is not possible. It is because Microsoft yet has not released the Windows 11 ISO file officially. However, there is a way still to download and install Windows 11 using the ISO file, however, unofficially.  And here we let you know how to do that.

Windows 11 is the latest operating system from Microsoft with the overhauled interface and other changes. Although Microsoft declared during the Win 10 launch that it will be their last operating system, yet, here is one more. The reason could be anything but we have a new OS with some key hardware requirements with which the standard users will not be able to install it on their system. They are TPM and Secure boot. However, all the modern PC motherboards and laptops already support these system requirements, but if you have around 6 to 7 years old computer then you might not be able to experience Win 11, once it is launched officially.

Well, there is one more way that is Virtual Machine, yes you can use either Virtual Box or Vmware player to install and experience Win 11 without any problem. We already have a tutorial on that- How to install and test Windows 11 on VirtualBox.

But wait... even to run a Virtual machine we need an ISO file of Win 11 which is not available officially, then what to do? For that follow this tutorial.

  1. Hi
    When I run the script a command prompt opens and shows the message: “Current directory contains spaces in its path. Please move or rename the directory to one not containing spaces.
    Press any key to continue…”
    and nothing is done. Nothing “Yes” button is appeared and nothing setup is gettting started.
    Why this happens?
    Does it need something else?
    Do I forget something else?
    Please, inform me to [email protected]

    • Simply rename the extracted folder to Windows 11, that’s it and you will not get his error again.
