So, some users might assume that they can no longer freely upgrade from previous Windows platforms to Windows 10.

However, users can freely download the Windows 10 disc image (ISO) file from Microsoft’s website with the media creation utility. Users can upgrade to Win 10 with that file.

During the Win 10 installation, users will be asked to enter a product key. Then they can click I don’t have a product key to install the OS without a product key.

Users will have then upgraded to an unactivated Windows 10. The unactivated version comes with some relatively minor restrictions. For example, users can’t change desktop wallpapers or themes within the unactivated Windows 10; and some of the platform’s apps will not work.
