One year back, when Microsoft launched Windows 8.1 for consumers, there was only one thing that everyone should have in order to get Windows 8.1. That is valid product key. Actually, Microsoft launched Windows 8.1 at partially free of cost. That means, you must have Windows 8’s product key to get Windows 8.1 upgrade.
There were different problems too. Suppose, you were using 32-bit version of Windows 8 and you had to use 64-bit version of Windows 8.1. There was no such option to pick 32/64-bit architecture. If you had 32-bit version of Windows 8, Microsoft offered 32-bit version of Windows 8.1. The same thing had happened with 64-bit version as well.
Apart from that, there was no such option to extract ISO image from the downloaded installation files. That implies, if you wanted to upgrade your Windows 8 to Windows 8.1 on multiple PCs, you had to download that separately. There were more issues for Windows 8.1 users.
However, after one year, Microsoft is rolling out the ISO image of Windows 8.1 and other major versions. No, this time, you can get the ISO image without having any valid product key. You can download and burn it on DVD or create bootable USB drive to install on as many PCs as you want. This process will let you install Windows 8.1 once you download. But, make sure that you have valid product key to activate Windows 8.1.
